Incremental import for individual tracks within an album

It looks like the incremental import will skip directories previously imported even when new files get added to these directories. Is there a way to use incremental import to check for already imported files instead of already imported directories? I have an incoming folder syncing from dropbox, so sometimes the tracks have not yet finished loading when I run the import. I would like to not have to manually check whether every album directory in the incoming folder has all of its tracks and simply be able to run the incremental import again to catch any stragglers. Is this possible?

Not currently, sorry! It’s tied to directories for now.

A tangentially related issue that would require similar rethinking of the incremental mode:

Ok, thanks.
