Cardsort source: # of groups

I wish the Cardsort CL had a source that detected the # of groups the student has made. I’m requesting this because, in the CL source “totalCorrectCards”, cards correctly sorted into an incomplete group count as correct. So if you want to check if the screen is completely correct, you also have to check the # of groups.

Alternatively, and this would be even better, I wish there were a universal CL source that detected whether the dashboard had marked the screen with a correct “checkmark” according to this answer key. That would address this current request as well as the old marbleslides request linked below:
