I have an AABA tune in which the key of the B pert is the dominant key, counting from the key of the verses. Of course, when editing in a given key, all I need to do is write out the appropriate chords and this displays and plays back correctly. But when I display in number notation, I want the tonic of the bridge to appear as 1, not as 5. Thus, I want, in effect, to select the B section of the tune and set the key to a different key from the verses, without transposing. The only thing that would then be affected is the numbering of the chords in the B section when displayed in number notation. I would add an annotation in text to explain to the reader what is implied.

Is there a way to do this?
