FlexCookie Rig problem

Hi everyone!

First of all, I am not sure if this question comes here, in this forum, if its not, please excuse me.

Ok, my problem is that I am trying to isolate the legs in the FlexCookie Rig, just to focus in the legs movement without thinking in the upper body. I see that is posible Appending (Instead of linking) and then hiding the upper body and its controllers as well

My question is: is it possible to do so, but with Linking? I mean I would like to be able to change between LowRes and HighRes and see only the legsā€¦ Is it possible?

Thank you very much for your answers!!

Come ooon!! Nobody know how to do this?
