You could merge all the files into one PDF then set up bookmarks or make separate songs within MS (each containing that instrument's page).
Or as you suggested already, use an appended title. I do this with different instrument keys of the same song—I add the instrument key to the song filename and title the song from the filename. I can search for the title and it will show all the different instrument keys of the same song, or I can use my instrument category if I want all songs for that instrument.
