appointment status options

Right now I am only seeing that we can make or delete session appointments. It would be very helpful and necessary to be able to mark sessions as late cancelations/no shows, rescheduled, or canceled, but so that they stay in the calendar with the adjusted status (maybe appointment is grayed out?). Related to that, being able to see the number of sessions, cancellations, etc in the client profile, to keep tabs on issuing fees, etc.
