I am sure you can. There would need to be a few more jigs in the process. It would be dependent on the paper thickness though. I did not notice the any marks on the back from the one I did. What you could do is set up another acrylic stamp such a number and then run them together, or individually. The only problems would either be lining it and keeping it together to where it is nice and flush. If I think of a solution for that, I'll see if I can add a second post as a sequel to it.
Thanks I appreciate it.
