Quote - My entire motivation is simply to make V4 usable to me in an animation, for the stories I want to make. The way Daz left her underarm makes this impossible; she looks unnatural both with arms at side and partially/fully raised.

Please keep in mind that Poser and his rigging system is limited and far away from being highclass. If one thing is fixed (with  morphs or mess around with joints and bends) another thing comes along. It is simply impossible to have one standard set for anything. Means, especially in animations, you may end up in a lot of work that needs very special know how. So it may be a better solution to go over to a more professional software.

A Python solution for all possible poses on all bending limbs for all important Poser figures, easily to handle even for beginners, is a doable and certainly a bigger project. I'm not sure if so mutch people are interested that it is woth the effort. Another thing is a solution for some special cases on a certain figure.
