Representing check-ins on Twitter

I'd like to set my preferences for how check-ins get represented on Twitter in the future. For instance, right now it doesn't seem to tweet out my whereabouts (only the shout-out). I think it sends a DM to friends with the exact address. But in actuality, it wouldn't bother me if some of the whereabouts would give the exact address. It would be great to be able to choose that as I check in. ex. {}give exact address {}just give place name {}don't tell anyone where I'm at.
