NOT option for groups?

[DaveSClegg]

Less of an issue, more of a question or suggestion if currently not possible, but is there a way to add a NOT option to a group filter? So I want this drive to map if the user is not a member of a particular group? Our environment has a number of network shares with mapped drives which all users except a few should have access to, and maintaining a small group of denied users is much easier than a very large group of allowed users.

I don't think this is currently possible with the code as it is written now (although I could be mistaken!) and while I might be able to write a new section that would do it, each time I updated my mappings via the web generator I'd have to remember to edit the code again, so if this was something that could be added in, that would be extremely useful!

Thanks
