Load more sms thread scroll back as needed

What I'm expecting is to scroll back through a message thread with someone and automatically have more and more load, which doesn't happen. I imagine it could work by using the count setting to give you an initial amount and join to send a push request to the decide with more history to pull that in. Make sense? Possible?
