Incredibly Basic Profile Question

Hello, I am brand new to SyncBackFree, and I'm trying to create a Profile for first-time backup. As I go through the Profile process (wizard?), it asks for a Source. But I have been unable to find a way to create a GROUP of Sources. For example, I can specify My Documents as a Source, OR the path to my Outlook.pst as a Source, but not both. A basic backup of user data would involve a dozen or so such Sources, of course. I would be very grateful if someone could tell me the trick, or direct me to appropriate documentation.
Thanks, Ed
