Motivation Idea

I was wondering if it would be possible to add a little checkmark (maybe in blue?) on the calendar to indicate when I do the Extra Credit Challenge.....It'd be quicker to see that on the calendar page rather than go back and see the green workout complete on the day's w/o page.

I know for me it would motivate me to do more of the ECC when I see the little blue ones.... Green and Blue...Green and Blue...Yes?
