combine one pdf and one image (stamp)

Let me assume there are two media sets having corresponding names.

mediasetA = [no01.pdf, no02.pdf, … , no10.pdf]

mediasetB = [no01.jpg, no02.jpg, … , no10.jpg]

I’d like to create a new “no01.pdf” that has overlay “no01.jpg” at the right bottom of the original pdf.

Does anyone know how to do it in Workshop (by TS)?

Otherwise, is it possible to create a new mediaset using two mediasets in code repository (Py)?
