Is it possible to edit whatever database NC uses for its chords analysis ?

Generally it is good but it seems to me that it has e.g. 'a thing' about E minor - in the piece I'm currently on, a chord of (from the bass ) G/E/Bb/E) which in context is fairly clearly a second inversion of C7 is tagged as Em or Em7b5, depending on how much 'choice' I allow it. Which reminds me that I had examples of the same thing in another piece a week or so ago !
