Is it possible to get notation to adhere to the key signature rather than the chord of the moment? For example, in a song in the key of Ab, I have an Eb played during a Cm7 and then the chord changes to a B9 and a subsequent Eb is notated as a D#, then goes back to an Eb when the chord changes back, all in succession in the same measure. Without having to manually edit every such occurence, is there a way around this?

Thanks,

Paul
