Master Behaviors (Based on AEs Master Properties)

Since I repeat a lot some Behaviors through different parts of the rig,
Would be nice to have some kind of Master Behavior:

A Single behavior that can be attatched to multiple layers,
If you change a property from it, it will affect all the properties from different layers that are attatched to this Master Behavior.

Eg. A Master "Cycle" Behavior, that will take care of every Looping animation.
