By the way, here's a Python script which will create a geometry insertion pose on-the-fly, within Poser.  Maybe it could be useful to you, I don't know.  It only works with the selected actor, but it can make experimenting with swaps within Poser easier.

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.
