[please find attached my SLDPRT file at the bottom]

I'd like to go from image-1 to image-2 (see below) in one step. Meaning I'd just like to change the text in some text-box, then click re-build and be done. Is this possible?

Edit: Just to further clarify, I'm not interested in embossing just ABCD and 1234. I'd like to be able to input any combination of four alphanumeric characters.
