UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Display name change for membership groups only?

I see on the admin panel a way to allow the users to change their DISPLAY names... On, Off, or with Ayth by admin, but I dont see any way to grand that permission to ONLY members of the supporting membership groups.

Is there any way to do this, and allow only the supporting members a way to change their display names (with my auth or without?)

Thanks.
