Putting part of an actor in another scenegraph (disregard)

I have an actor that I would like one part of to be under one scenegraph, and another part to be in a smaller isolated scenegraph.
I was thinking of using instanceTo and then hide one of the parts in each scenegraph. Is that the most efficient way? Is there a better option?

Update: Apparently you can just reparent a piece of geo out of an actor and it will remain bound to the skeleton. Case closed.
