URGENT: PLEASE MAKE AN END-DATE FEATURE AVAILABLE IN THE CALENDAR AND SELF-SCHEDULER!

PLEASE MAKE THIS FEATURE AVAILABLE! It is a very basic functionality that every calendar app I know of has! Literally, the recurring feature isn’t useful at ALL to me unless we can have an end date! My practice has a policy that clients cannot self-schedule recurring appointments UNLESS they have an end date for it. I do not allow indefinite recurring appointments! So I literally cannot follow my own policy using your calendar! This will become a BIG problem when I turn on self-scheduling! For now, since there is no end-date option on calendar events, is there a way for me to turn off the recurring feature in the client self-scheduler?? Because I cannot have clients make recurring appointments with no end date! HELP!
