NAS Multiple FOlders

I currently have 3 different folders on my QNAP nas.  (VIDEOS, ITUNES, IPHOTO).

Is there a way so that the wdtv live hub can access each of those folders seperatly.  For example, I jsut want the photos part of the OS to grab the photos from the iphoto share.  For viseos I want it to grab them from the videos folder etc…

Currently, if I log in to the smb account, it shows all 3 folders at once and wont allow to sync up each folder individually.

You could use a different username for each, I believe…

I thought of that but it just lets you log in to the nas once.  When I tried that it would wipe away the other share.  Kind of stupid.
