Thanks to everybody for responding. It reminds me that I've learned most of what I know about Poser right here in these Renderosity threads.

I don't want to impose on Ockham's Python expertise, and I'm not comfortable enough with magnets to try Les's insightful suggestion, but I've played around just enough with grouping in the Cloth Room that dadt's and svdl's proposed process seems the most suited to my mid-level skill set.

Thanks svdl for listing the proposed method in a step-by-step format. I will give it a try and report back with my results.

Thanks, and Happy Jiggling,
Richard
