Yes. Set Labels to "Intervals (1 2 3)" and every note shows its scale degree instead of its letter name — C major reads 1 2 3 4 5 6 7, A minor pentatonic reads 1 ♭3 4 5 ♭7, and Lydian correctly reads 1 2 3 ♯4 5 6 7. Pick "Roman (I II III)" for Roman numerals instead. Degrees are counted from the key you selected, so the same shape reads with the same numbers in every key — which is how you learn a pattern once and move it anywhere on the neck.
