For the appointment limiter, in the calendar appointment view, can it only count the number of sessions used on the current referral (up until today’s date), not counting any future appointments?

Can there be a little icon on the front of the calendar appointment to show number of sessions used on limiter as of that date (rather than clicking into each appointment to see how many sessions have been used on the referral)? Can there be a warning message in the client file view that there are no more appointments left on current referral?
