USER table - any other placement?

I trying to figure out the best/easiest way to assign users to a certain branch.  At first I simply inserted their respective Branch location name into the beginning of their User Name description thinking that I would be able to link to that.  Apparently the USER table isn't a regular table and perhaps a datapipe?

Anyone have a suggestion of what they might do?  I can't seem to link to it from Crystal reports (unless I'm just blind).
