Offline files and synchronization

OK, here's the problem, I have all these subfolders which are different years
(2005, 2004, 2003, etc.) which I need available offline. I'd like them all
mapped to one drive, so I have V:\2005\, V:\2004\, V:\2003\, etc. So far
no problem, I can do this either by making the parent folder (which is
shared) available offline, or each individual folder. But I want to be able
to synchronize them separately, as they are very large and I thought making
them available offline individually would allow me to do this, but when I
start synchronization, it only lists the parent folder, rather than each
individual folder, which is what I want. Is there any way to do this?

Also, it seems like I can either make a shared folder available offline, or
an immediate subfolder of that shared folder available offline, but no
sub-subfolders available offline (at least not without anything above it
available offline). I've made the group policy change to make subfolders
available offline by the way. Is this the way it should be?
