Retriggering flashes - lights freeze

Hi,
I'm trying to set up a chase to do a flash.
I have two scenes, the idea is that the first scene is the flash (all lights full bright), the second is the scene the flash fades to.
I have set a 0.5 second fade time and this works quite well.
Except....
If I retrigger the flash before the fade has completed the lights freeze in a half faded state, what I'd like is for the flash to retrigger.
The flash is quite slow so I would like to be able retrigger before the fade completes rather than wait for the chase to complete and then retrigger
Thinking about it - is a chase the right thing for this effect ?
Thoughts ? TIA

It seems my problem is a little more fundamental
I'm using the virtual console with keys mapped through OSC so I can use a python script to control the selection of scenes and chases programatically.
My script sends keys through OSC to select the lighting required.
The effect I'm seeing is that if my script selects the same scene twice in a row the second select turns off the scene - I need it to just select the scene again.
I can add some code to suppress a key code if it's the same as the previous one for scenes, but that feels a bit kludgy and still leaves the issue with chases that are stopped rather than restarted.
The problem is that each keytroke received will toggle the scene or chase on or off - what I need is to just select the scene of restart the chase.
I understand that I have the toggle option selected in the virtual console but I can't see an option to reset/restart the scene or chase
Is this a fundamental problem I'm hitting ?
TIA

I'm having a nice little conversation with myself here..... someone may find it useful
I've found a way around it.
- If I select the same scene twice, I don't send the key press
- If I select the same chase twice, I change the capitalisation of the key sent(anything would work but this is convenient), and select an identical clone of the chase, but since it's a different key (and different chase) it restarts
it's a bit messy but seems to work OK at the moment

After more testing it seems this won't work for chases
scene1 - red wash
scene2 - flash green
chase1 = scene2, scene1 (with 1s fade between them)
Take the situation where Scene 1 is active
Chase1 is triggered, but because the last scene in the chase is scene1, it toggles scene1 turning the red wash off.
It would seem logical that I could use scene2 on it's own and after the flash return to whatever the setting was, but I've tried scene2 with a fade out time, but the fade out time is ignored - in this case I need a slow fade for effect.
All my issues seem to be down to the fact each time I select a scene (or chase) it toggles the state (on/off)
Is there a mode I can set where selecting a scene a second time just re-selects the scene or chase and doesn't toggle it on and off ?
So close but I'm now completely stumped - please don't tell me it's back to the Arduino.....

Would this solve your problem?

Hi, thanks for the sample, that's the sort of thing, but I think it still doesn't quite deliver what i need
However I have discovered that the 'solo frame' goes some way to helping me out, maybe with a combination of programmatically suppressing sending the same key press twice and duplicating all the scenes and chases I may have now found what I'm looking for.
It feels a bit clunky, so I will ask, Is there a reason there is no option to retrigger scene/chase in the virtual console button properties ?
Is it something that other people would use, or is it something that is more gig oriented ?

I'm not a developer, so i can't answer that question. Probably nobody asked for it before, or the developers didn't have time to implement it. I think it would be a useful feature.
Anyway, if you'd post a workspace where i can see what you are trying to achieve, i could try to find a better workaround.
