If you use a template and mark the end stitches, you can split. I remember seeing full jacket backs done with the first embroidery machines - only had 4x4 hoops. I had the info but sold the books. I have digitizing software so I can set position stitches and split there.
This is older than the hills, but the this is the way it used to be done. It's for a Pfaff, but the splits were manual. I'm surprised the site is still around.

If you want software, there are now less expensive solutions to splitting. Embrilliance, Buzzedit, Embird, and the Amazing designs app that Jenny is using.
