Music Track - Original Release Date

Would it be possible for a feature to enable the adding / editing of track ‘Origninal release dates’. This would be particulary useful when using the Focus feature on compilation albums whose release date will not neccessarily be that of the music track release date

I agree. I want to be able to focus on tracks released for a particular year/decade, and compilation albums with tracks from different years don’t work for this. Can this feature be implemented please?
