I hope I can get this to make sense and be concise.
Is there a way (or if not - could this be considered) to have upon ADDING books - it to FIRST look to see if there is a FIELD with info in the file already - to get the metadata (i.e. Author, Title), and IF NOT - to then fill out that field from the Filename?
Sometimes I have a set of added books (PDF's in particular) where SOME in that set - have the PDF info set for those fields - but not all of them. Whereas the filename may have at least SOME of that information in it (the issue comes from having limits on the lengths of the filename - so in that case - the WHOLE name is not necessarily there - but MAY BE in the PDF itself).
That's the scenario that this question/idea came to me from.
