group intensity control when running a pixel map layer

Howdy all,

i have a bunch of led wash movers that i have mapped and it works great for low res colour sweeps and chases etc, but is there a way to make my group intensity faders work? i can make a pixel map layer group on a fader and fade the intensity of them all with that but is there a way to use the group masters i have so i can individually fade out groups?

I'd also like to be able to override the colour information coming from the media file?

thanks, newb questions :)
