Roon doesn't update albums where quality is increased

If I add a folder/album to one of the watched folders, it pretty quickly appears in Roon under the latest additions section. If I replace an album, say MP3 with a FLAC version, then Roon does not seem to update and keeps the MP3 version in its database until I manually rescan the folder. Can this be fixed?

I have the same problem but replacing 16bit with 24bit FLACs.

Just noticed this topic is in feature request - should be in support I presume.
