Calendar: Difficult finding a type of appointment availability for a physician - monthly view

Can we have a combo (checkbox & dropdown) filter in the monthly view of the Calendar so MOAs can identify availabilities for the preferred specific 'appointment types'?

After they select a particular day, if the appointment time doesn't work for the patient and they click the "month" view again, please remember the 'appointment types' previously chosen in this new filter so they dont' have to select it all over again.

And perhaps beside this new dropdown, have a "select all" function so they can quickly choose "all" appointment types again.
