No more than 2 slots available for services

Hi, 

I am currently having an issue with bookings in which I have defined one service for every member of my team. They have different schedules, but some days there may be 5 people at the same time working. However I don't want them to be all on meetings at the same time.  Is there an option that allows me that, if two members are scheduled on a meeting on a specific day and time, the other services calendars are unavailable to book? 

Thanks, 

Carlos
