Possible to bulk import tags?

I'm trying to update the tags for my audiobook collection. I've downloaded a tag source that searches Audible to find matching books. This seems to be working great. The only issue is I'm having to do this one book at a time, and I have well over 1,000 books. Is there any way to automate and/or streamline this process?

Unfortunately not, it's working on a per-album / per-audiobook basis.
