De-Dup Product Improvement

I have a large collection of mp3s (150,000+) & am very happy to have De-Dup to remove duplicate tracks.
However, it consistently returns the same approximately 50 false positives (ie. pairs which are definitely not duplicates) every time it runs.
Would it be possible to add an "ignore this pair" button for subsequent runs?
You appreciate that it wouldn't be enough to add an "ignore this track" button, as this wouldn't allow for detection of new duplicates involving this track as fresh material is added to the collection.

Click the 'x' in the top right of the found duplicate to hide it.

Thank you. I have no idea how I missed this.
As I'm sure you know ... it's almost impossible to underestimate the intelligence of users!
