Suppose I would like to enter a group of black notes, and then enter a different group of blue notes in the same fretboard. I can't figure out how to do this. I know how to change the color of the second group after I add them, but when I first add them they are black and I have to select the ones I want to change among all the black ones and this gets tedious and error-prone. I'd be very grateful if someone could tell me how to set a different color for the next group of notes. Thanks!
