Many of my song files are exported from Finale, MuseScore or .DOC files. I take notes during sessions or rehearsals using MSP annotations and want to integrate these notes later into the original files and create the corrected PDFs once again e.g. to share them with others.

That's also a kind of database maintenance that I do at home when I have time. So performance or caching is not an issue.

Creating a list of cropped / not cropped songs is not my main concern as more or less all my songs are cropped. I create the PDFs with margins that are wide enough for print-outs and crop them in MSP as soon as I import them.

How about implementing special filters that can execute an SQL statement?
Those filters could be stored and named similarly to the existing storage of filter combinations.
