Global Keystone on Each output

I don't think a solution exists already for this, but here it goes. Can there be a global keystone feature for each main output (not necissarily for the sub-mixes)? I find it frustrating that in order to have 4 layers playing on one output with keystoning adjustments, I give up my Visual FX parameter on all of the layers.

possible solution:
Allow the user to make the decision if they want to have a global keystone or not. In the DMX Assignment window on the GUI, allow the user to select a new deivce that is a global keystone for Output 1 or 2 (same concept as the assignable device for volume control on each layer). A new profile would have to be written for consoles and you would need to figure out how much you would want to include for control (Scale, Rotate, Position, a.k.a. how many DMX channels you want this device to eat up)


Thanks for listening

i have a solution for this that im testing at the moment.
