I was wondering if there was anyway to separate address books that get sync'ed through DM?

I am an Outlook 2007 user using Gmail

What I'm trying to accomplish is, and because I use the blackberry as a phone and data device, to keep contacts that don't have email addresses out of Outlook 2007. Is there any way to accomplish this to prevent the sync process from adding the 900+ people that I only have phone numbers for to Outlook?

Does this make sense or is it wishful thinking?

Happy New Year
