Fade request

[DJMan32]

I have an effect I am trying to generate and need either some out of the box thinking or a feature added. Say I have a a solid white scene on all fixtures. I want to fade to a world shutter chase but I want the change mapped to a fader. when you ramp up the fade time on the blackout chase the desired effect works however I want full control of that fade because sometimes i don't want it to fade completely. This almost sounds like this could be a new scene option, scene on fader or something like that where instead of a click on click off, it is controllably ramped on and ramped off. Great for colors and relative movement modifiers as well.
