I sometimes play along with a clarinet player who, while she can sight read and transpose, it would make it incredibly simpler if i could simply have her melody line transposed +2 while my guitar chords (above the melody line) remain the original.

An example would be Unchained Melody, first chord is C, firs note is C, I want the lead sheet to read first chord C (for me) but the first note to be D (for her)

At the moment, if and when I transpose, it changes both so I have to create two separate charts and subsequently update two separate charts

thank you
