identify songs that were uploaded and not available through apple music

The vast majority (95%?) of my iTunes Match library is available through Apple Music. So, I'd like to unsubscribe from Match (since I really don't need it, except for the last 5% of my library).

Before I unsubscribe, how can I isolate and download that last 5% of my library (so I can store it locally, and then, coupled with Apple Music, have all the music I always had)?
