Backend Replies Creation/Editing

I was very happy to see backend discussion creation/editing with the ability to assign a user to it. This helps greatly with migrating from forums that don't have a migration tool. However, it is still not useful because this functionality doesn't extend to replies (at least, not that I could find). Could you pleased extend that function to replies (or tell me were it is in case I missed it).

Thanks for the good work.
