Add article to transactional publication without generating new snapshot

Using SQL 2008 R2 transactional replication with pull subscribers, when we add an article, I'd like to avoid having to create an entire snapshot (the db is ~80 GB, so this takes hours).

From this article, I've seen how to do this with a partial snapshot by setting immediate_sync off, but that didn't work for us.

Ideally I'd like to just run this as part of our db script to create the table, so if we want it replicated we do:

Create Table ...    
sp_addArticle ...    
sp_PushThisToOurSubscribersNow
