Quote - you can also set up a pz2 file to switch uvmaps / geometries

Do you mean, by switching the figure geometry reference?  When I tested that, it worked but the change wasn't written out in a saved file.    Alternately, you could use a pose to switch each actor separately, but then you need to have all the alternate geometries separated by actor, as you would with dial-driven geometry switching.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
