Is it possible to set up a shop so it has multiple levels?
Eg House items room by room - Light fittings, power points, switches > bedroom 1 same etc for bedroom2 Lounge etc.
Resulting in >> bedroom1 : 3 lights, 1 power point / bedroom2 : 2 lights, 2 power point and so on?

All the items are availbale for all rooms but need to be separated so can be added to or deleted by room.

Any ideas how to proceed appreciated.
Thanks
