Homework field in schedule, planner and diary

Hello
I set and collect homework at regular points of my 2 week cycle.
Would it be possible to add a field in schedule to remind me to set or collect homework. This should be visible in planner and diary.

I am using location for this but its not ideal.

Hi,
 Sorry for the delay.
 It is in my to-dos!
 I hope to get there soon.
 If you miss anything else, do let me know
