Assigning different types of short forms - how to go ABCZ, please?

I started abbreviation expansion some years ago with AutoHotKey, using John Knowles' ABCZ abbreviation system. When I changed to IT5, I was able to "massage" my glossaries into ABCZ with an external helper program that came with it.

Now, after a break, I've just started using 7.20 Build 2011-11-04. Please, does the "massaging tool" still exist? I can't find it, though I think there's a mention in the Help file.
