Remember that bone creation, except for body handles, requires editing the basic OBJ so you can't readily do the job in place anyway (POser does, of course, have the grouping tool). Also remember that you can copy from the selected figure into Skeleton Setup, make changes and paste back into the scene. I like the SS approach, but I'm mainly working on props where the bones aren't necessarily attached in a stick-figure like way as they are for organics and clothes.
