Second Address Book Folder

Does anybody know if it's possible to construct a second Address Book in Vista? When I used XP I opened a new folder in the address book and I was able to fill it with seldom used contacts. It was very handy being able to switch to a second list of contacts when I needed to. In Vista, all I seem to be able to construct is a Group Contact mailing list which isn't very convenient unless all you use it for is group mailing. I really miss having a second address book. Hope some person more enterprising than me has found the solution. Thanks.
