One booking per same worker in the same time
I have 1 worker with multiple services (multiple connections). All services have duration/slot step = 60/60 (1 slot). If I book a service at 12:00, I can't book again same service for this worker at 12:00, but I can book another service for him. What I need is that when any service is booked for worker to block bookings for him until that service ends, let's say until 13:00, in this case. Is that posible? Thanks.
