Chord Crush - How to drill Major vs. Minor specifically

Hi.

Is it possible, and if so can you explain how, to specifically drill Major vs. Minor in Chord Crush?

I see in the custom area many options for various qualities/extensions -within- either Major or Minor, but I don’t see how to set up a drill specifically of Major vs. Minor itself. (i.e. Major vs. Minor triads, Major vs. Minor 7th chords)

I know the general drills use both Major and Minor, and so could be considered to cover this. However, like any other bit of musical perception, some people would benefit from (read NEED) extra, repeated, specific drill right there.

I’m hoping there’s a way to configure this currently, but if not, I certainly suggest adding it.

Thanks!
