Resources reservation and split rooms

Is there a way with resources reservation to manage multi-rooms?

Exemple:

I have a large room name C composed by room A and room B (separated by a portable wall). Can we automatically set the status of room A and B as booked when we reserve C.

We have the same situation. I just entered each of the smaller rooms with a note to book both if the large room is desired.

Sounds like a lot of work to program two rooms as a subset of a third.
