I'm new here, so my apologies if this has already been asked and answered.

I see that CAGED is the default fretboard organizing sytem here. It's a good one and I have no complaints about that. However, is it possible to add another one? I enjoy the "Fretboard Roadmaps" material of Frek Sokolow as well as the "shape system" of jazz guitar legend Herb Ellis. They used 3 main shapes (for major chords): F, D, and A. (For Herb Ellis, the "A" could also be called "G" because the "G" shape and "A" shape share the same partial barre. Herb refers to the shapes by numbers, not letters, but that's another story.)

When using only three shapes, they lay out easily on the neck and connecting them becomes easy soon enough. There's less overlap than with "CAGED" shapes.

Can one program that into Neck Diagrams so that you could get, say, the "F" "D" and "A" shapes of Bb all laid out on one fretboard grid?

Thanks for listening.
