Well then let me give you my idea. Bear in mind that I do not have Pose Magic so this is more of a general idea/tip.

Use the memory dots. Do the main pose, then set a dot. Pose the arms or whatever, save a partial pose, then revert to the previous pose by clicking the memory dot again

I  think that will work - at least if I understand your question correctly :)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
