That’s exactly how I do the pantos..I lay my pattern on the table behind the machine trolley. I use a usb rechargeable laser that I’ve attached to back side of machine, and also attached a handle to the back of my trolley. It’s a large handle like you find on institutional doors ( my FIL remodeled a hosp & was given some parts that were replaced in the building, ie door handles). I’ve
enjoyed my setup so much more. I’ve loaned use to a couple of friends and they had no problems using . I hope you have such table space behind your machine. Good luck.
