How can I enable combined rental?

For example, do you have a room that you can also partially rent out/rent? Or is a certain room always linked to another room? Then work with resources.

The resource is the physical location, the product is what is rented.
Creating the resource manages the availability of the products.

For example:
You have 1 large hall that you also rent out for half: hall A and B. If hall A is rented, the large hall can no longer be rented out. You arrange this with resources.

In the above example you will therefore need 3 products: large hall, large hall A and large hall B and 2 resources: large hall A and large hall B

You then link the product large hall with both resources.
You link the product large hall A with the same resource, the same applies to B.
