It kind of is... Just copy and paste the building. Then slowly add the IDs for the premium houses. Then add whatever else is needed to make sure the houses don't fuck up and are raidable... So yes it is easy. Staff just don't want to do it... If you can do it on 1, you can do it on 2,3,4,5,6. It might take some time but it'll help...
That's how their made. Its not a complicated process. The only problem you have (or the staff who do the ids in this case) is the time it takes... So yes it is EASY. Its just TIME consuming.
Your ignorance is amusing, you know nothing about how anything works. So stop making demands like this and over simplifying our jobs because you have no idea what we have to do on a daily basis.
