So I've got a bunch of shared addressbooks from one account out to many people. Let's say I've got 3 addressbooks, 1 of mine, and 2 shared. Let's say I want to add a contact to shared addressbook #2. How? It looks like the iSync connector syncs many to one, but you can't really go back to a specific one unless it's already there? Sort of forces you to use the web client for anything more than basic updating. Thoughts?
