Define maximum number of meeting per day on a agenda

As Sales I would like to make a maximum of 5 client demos meeting per day, because I have also have to make client call.

As a support team, I would like to make a maxium of 3 product training per day because I need to answer a lot of email as well.

Both would like to display as much a possible slot on their agenda for customers but don’t want to spend all the day on meeting
