Block dates that have already sold out

Hey guys. I’m using the Air Date/Time Picker plugin and would like to know if a configuration is possible. My application is a scheduling system and within days it has certain times, I would like to know if it is possible, when all times for that day are scheduled, if I can block them. Example: On the 8th I have two times, at 8:00 am and 9:00 am, but two people have already marked them, so the 8th is clickable on the calendar. Does anyone know if it’s possible?
