no unfortunately renaming isnt the issue, the issue is that the V4 Base has a set of readscripts that tell poser to go to a certain spot and collect the morph channels found there, and load them. as soon as you save the figure to a new cr2 or pz3, poser saves the morph channels and not the readscripts thus freezing the figure from being able to add new channels. you could manually add those new channels but it would be a royal pain to do so becouse you would have to add the blank channels to each bodypart.
