Naming projects

Hi, I’m a video editor who frequently edits youtube shorts for customers.
Say I’m creating 10 shorts at a time for one customer, then 5 shorts for someone else, then 2 shorts again for customer 1. Does every short count as a different project? How do I name projects for the license, seeing as they’re all just shorts, and are pretty much the same with similar topics?

Yes. ( different end-product )

short-movie-1.avi > license 1xxxxx
short-movie-2.avi > license 2xxxxx
