Yes, the properties of a zone can be scheduled in a scheduel of zones.
But i want to schedule objects, filtering them by the properties of the zone they are located in.
This is possible in a limited way, as I explained - we can filter by zone name, number and type, but at least the first two are usually reserved for other purposes, and zone types are a very limited option for this kind of filtering.
So why can't I read more information from an objects' zone, than this very limited set?
