I discovered this trick naerly a year ago. I've not developed this because it requires you to hand edit every file involved, changing the :##'s lines to what they should be. It is an enoumous pain and because of this limitation it won't work with pre-existing figures. If you are building a collection of clothes (Like the Tannis costume I made) it's useful there because you can count on Vicky being labeled as "Figure 1" with ":1" on all the body parts.
It also allows you to SuperConform clothes in P5, though I've found a way to get the super conforming effect without the Read Script Jazz, but it's a heap'o trouble too. I never thought I'd miss cross talk, but I do.
