Graphically annotating MS scores

Almost every score I upload to my MS profile has a cover page. So vertical frames & text (and graphics) placed inside a frame, I can handle. I have a series of scores I want to do more with.

As I understand it, what I upload to the .COM repository are limited to scores from MS. I'm not aware of being able to upload a stand-alone .PDF, .PNG or whatever else.

Where i'd like to get to, is shown in the image attached here. I'm not sure how to accomplish this but keep the file I upload - a SCORE file. Suggestions?
