Where to set a Mother-child setting in listings?
Since this month i'm renting out a huge 3-storey holiday villa. In the high season i want to rent it out as a whole, but i guess demand for a huge villa is to low in the off-season so i want to rent it out as different apartments (each floor as its own apartment).
Now i made a listing for the whole villa, which is online for a while. I now made a new listing for the 3 apartments, which are also online. The apartments are only bookable from 15 Sept.-15 May, but the whole house is bookable for every single day. I want to setup the system in such a way, that if one of the apartments is booked those dates will be blocked on the calendar of the entire villa.
I believe i've seen such an option to setup a mother-child listing relationship on the extranet somewhere, but i can't find it anywhere anymore, and neither can i find it in the help contents or with google. Can anyone give me directions on where i can find these settings?
