We have about 400 rooms that we can book in our system. Some of them have the interesting feature to be modular. So a large room can be split into 3 or 4 rooms. (see image) because of this we have 2 options of entering the rooms. The walls are collapsable so there are a total of 6 configurations. 

1. one room
   1. no chance of overbooking but someone who needs only one section may take it and keep the other rooms from being booked.
       
2. 6 rooms
   1. a chance of overbooking because of the combination overlaps. 

Is there a tool (plugin) that can apply logic to a set of rooms to say "if room A is booked then B and C are available" or "if ABC is booked then none are available"
