Supervisee Notes - track completion of progress notes.

I supervise two associates and as their supervisor I must review and sign their notes. It would be helpful if once the supervisee completes and reviews their notes, that there is a check box or something they can click so I know on my end (maybe it changes color for me or I get an email) that the note is ready for my review and my signature as currently I have to go into the calendar and keep checking each note and I am left unsure if they have reviewed/edited them yet or not.
