Could we change how Rock Climber works so that we can turn on specific pentascales and scales?

For example, my beginning students are required to know all white key major and minor pentascales (ABCDEFG major and minor).

Quizzing them on the majors is fine, I just set it to a maximum of 1 flat and 5 sharps.

However there is no way to also quiz them on minors, because I would have to set it to a max of 4 flats and 2 sharps.

Would love to see this improved.
