Why don't you do what they suggest when doing FMQ or hand quilting -- bring the back thread up to the top, then do your stitching. When you finish your stitching, don't use the autocutter, leave a tail and bring the back thread up to the top. When you get finished with all your stitching, take the two threads and tie a knot close to the quilt top, then using a self-threading needle, insert the needle close to the knot and go through the batting about an inch, "pop" the knot into the batting to bury the knot and clip the thread. That way, you know your stitching is secure on both ends.
