Q Light Controller+

Is it possible to offset a channel dmx by a fixed value just before output?
Example:
A moving head has multiple gobos and a focus channel.
Each gobo needs different focus settings for the same distance, so I create collections for each gobo containing a gobo scene and a focus scene.
Now, for the set distance, each gobo will project with perfect focus accuracy, thanks for my collections adjusting it for every gobo.
But if I change the venue, where the distances will be different, I will require an offset to the focus values for it to work again properly.
Can this be done in QLC+? Ideally, with a slider working as an offset.

In every venue I come, I have to alter all the base positions - no big deal.
Where the focus is important, or you can use channel modifiers: https://www.qlcplus.org/docs/html_en_EN ... rties.html, which is a fixed solution.
Or you can use a slider for the focus (as you requested) put a fader on your VC and put it in level control. Now select the focus channel as a controllable channel with your fader.
Doesn't focus change in function of the depth of projection - so every position needs some kind of focus? Right?
