Most of those sites are pretty uncommon or rare at best. And sites can't be modded, at least not in Dom2. Then there is the problem that climate controlling mpas via such sites gives automatic guaranteed gem income of a specific type. That's often not desirable, and it's a rather clumsy workaround. I've used it in the Faerun maps, and I'd rather not do it. That's why I asked for this feature, because then it might at least get considered. Not asking is guaranteed to get me nothing, after all.
