Fetchart only if no embedded art?

Is it possible to only fetchart if there is no embedded art? I have a library that I’d like to only have embedded art. I see the logic as something like this, ideally all run during import and possibly after manually for library clean up.

  • check audio file for embedded art and possibly check art resolution/quality
  • if no embedded art, or fails quality check
  • fetchart
  • embedart and remove_art_file: yes

I don’t think there’s a perfect solution to this, but you could imagine doing extractart to get image files in the filesystem, then run fetchart (which should hopefully now skip those albums that already have art?), and then embed.
