Limit TOTAL number of bookings across multiple events

It seems like there are several threads with related questions but not exactly this one, so my apologies if this has been answered elsewhere.

I have multiple events on my calendly (15-min, 30-min and 1-hour meetings), and I would like to limit the TOTAL number of meetings people can book in a day, regardless of the length of the meeting. For example, if I want to limit my meetings to no more than 3 per day, even if those three meetings are 3 15-min meetings, 1 15-min and 2 30-min meetings, or 3 1-hour meetings. 

Let me know if any one has any thoughts. Thanks so much!
