Fixture without Master Dimmer

[davide]

Hi!

I've some stupid led pars which have only red, green and blue channel without the master dimmer.
Is there a way to create a "software master dimmer" fader which works like the grand master fader, but only on color channels of a single fixture?

I hope I explain well my idea.

Thank you so much!

On a similar note, would it be possible to assign a slider to be the master of a solo frame for example?
