Auto-import externally added ratings

I rate tracks in Mediacenter 25 by JRiver on macOS. Rating them in Terminal is a step too much because I have to switch to terminal whenever I hear a track that I like.

What I would like to achieve that a smart playlist is generated from tracks that are rated 4-5

    playlist_dir: ~/Music/Playlists
    auto: yes
        - name: '4 or 5 stars' 
          query: rating

But I guess I would need some auto-import functionality for only the rating field.
How would one go about achieving this?

Hmm; maybe the beet update command is what you’re looking for?

Of course, overlooked that in Read the Docs. Thanks!
