Quicker? Why would you need that? It's not as you will actually be sitting there, for 30 actual days, as your character creates a magic item. In all likelyhood, you're either going to schedule that magic item creation session for the day you can't make it to the session, so the rest of the group carries on without you, or the entire group is going to sit around and wait for you to do your magic item creation, perhaps while attending to some background task of their own.
And you want to burn a feat for this?!?
