Fader group master feature request

Now that fader objects are available on Magic Sheets it would be very usefull to be able to assign a group of fader objects to a single fader object to act as a master fader for just those faders. This would allow a "2 scene preset" type of operation on a magic sheet useful for simple one offs and training. With two sets of duplicate submasters assigned to the two groups of faders, a pair of master faders could do crossfades and pile ons. It would helpful to have a reversed fader object (100% bottom, 0% top) to use for A/B fader pair operation.

The fader object is mentioned in the release notes for 2.3.3 but there is nothing in the manual supplement. Is there more information somewhere on how it can be used?
