This may seem unnecessary, but is there any way to place two notes on the same fret and string? I am trying to illustrate the overlapping blues boxes based on Pentatonic scale. However, I want to show every box formand how they overlap. Ideally box one would all have notes labeled as 1, and then where box two overlaps there would be a second note marker with 2 on it (and would use a different color). Same for box two and three and so on through five.
Obviously I can show the overlaps with single notes, but then the box shapes don't stand out.
