Okay - some progress. It seems P11 is very fussy about which library folder is open - some cause the "new set" pop-up ... some do not. So I can add them into some odd place I don't want ... but obviously can move via file explorer later.

Second wrinkle - despite the props being parented to V4, they save as "parent UNIVERSE" in the new pp2. So I did need to edit the new pp2, changing this to "smartparent lForeArm:1" and so on, for each item in the new bundled pp2.

(As a side, I'm still a bit fuzzy about the lForeArm:1 vs lForeArm:5 - why 1 or 2 or 5? Most of the original jewelry PP2 had a ":2" after each actor ... except one file had ":5". I just changed them all to ":1" in my bundled PP2 and P11 seemed to take it fine.)
