Paid Subscription as Secondary Usergroup + Display Usergroup

[Awjvail]

Is it possible to have a paid subscription usergroup be a secondary usergroup + the display usergroup, leaving their primary usergroup alone?

It's very annoying to have to go fix peoples usergroups that buy paid subscriptions, which puts them out of their staff etc. usergroups. :S

I've looked in subscription manager and there is the option to put it as secondary usergroup, but no option that I can see for Display Usergroup.

Any mods to do this or whatnot?

Thanks.
