I have a couple of business documents that are updated on a regular basis. I also add notes and highlights to the book. Each time I load the updated book it comes in as a different book - it doesn't overwrite the old version. I usually just delete the old version of the book, and of course all the notes, highlights and bookmarks are gone.
Is there any way to have the new version overwrite the old version and maintain the notes, etc.?
