Since I prefer to sew my bindings to the back and then topstitch down on the front side, I've never looked into doing it on the LA.
I use the back of my LA table to lay out the quilt (one side at a time) and trim it, then I take it in the house and sew on the binding to the back, flip it and topstitch it to the front. Even a king size quilt does not take very long to get a binding on. I'm one that use to hate binding, and now it is no big deal.
