You might be able to think of bookmark import options like import with the assumption the next bookmark is the next song, no import of bookmarks etc.
Some publications will start a new song on a new page (the PDFs I prepare do this) and others with a song starting on the same page as one ends so an Edit mode would be useful to check and update once imported.
I find it very slow to create the individual song bookmarks from a PDF within MS so do it on computer.
