Add Colors/icons in calendar?

Hello there !

It would help quite a lot to have the possibility to change the colors of the calendar and/or add icons. For example, set a red icon with up arrow for upper body strength workout, a red icon with down arrow for lower body strength, etc.

That would help plan out our workouts during the weeks, and see if there are too much upper bodies, not enough core, etc.

Feel free to comment !
