If you see the name of the channel in the CR2 (or the subfiles that the CR2 calls via readScript commands) you can write a pose file to unhide it, e.g. this one un-hides the scale dials in the Hip actor.  If you download this file, rename it to just "RevealHipScale.pz2", it isn't really a jpeg file, it's an ordinary Pose file (plain text).
