Hi There. Apology if duplicated question here. Is there possible if i can make an appointment to book for multiple slot? Example: I got only 4 slots available for each timeslot. Lets say 9am to 10am, meaning during that period, i can only serve 4 customers). When customer make an appointment, they would choose if how many person they are having, from 1 to 4 pax, and once the appointment is submitted, the remaining slot show be deducted based on the number of pax. So lets say Customer A make an appointment on 9am - 10am with 3 pax, so the remaining slot should displayed as 1 and the next person choose the same slot can only choose 1 pax.    How can i achieve this?
