Limit number of bookings

Is there a way to limit the number of appointments that can be booked per day?

Ideally I want my clients to be able to book a time that suits them but limit the number of clients to 3 a day. Once that limit has been met (for that specific day) the bookings calendar shows that day as fully booked.

Has there been any movement on this? Is this possible yet?

Have there been any updates on this question?
