Limit on Data per Data Cell

Hi! Just here to ask a quick question.

I have a desk booking system in place using a Calender. I would like to limit how many people can book in on one day, is this possible in bubble?

I.E. only 5 people can book in on one date, e.g. 22/10/2020, once their is five entries with this same date then pushing a notification that stops the user booking as it’s full? It probably sounds better in my head!
