Tool to manage Windchill product team membership en masse

Has anyone seen or purchased a tool for managing product team membership in Windchill en masse?  The tool should allow “admin” users to add multiple principals to roles of multiple
product teams at the same time instead of having to add them one product team at a time. I’ve briefly scanned the fishbowl Solutions and Software Factory sites and will be contacting them, however initially it doesn’t seem that either offers such a tool.

Thanks!
