Need guidance on cleaning up Roon library and re-importing files (ref#KHNPWX)

I’ve moved your post from Support to the Feedback section of the forum, since your question is not one that the Support Team will be able to deal with.

All Feedback posts are read by the Roon Labs team.

The issue is, as you say, longstanding, and there is already a Feature Suggestion request. You should add your vote to it.
