Dwellings of tier 4-7.

If I understand you correctly, you need to place the Random Dwelling Level 7 object (random dwellings), and then select it. On the left, you will see two lines you need: Random Creatures and creatures enabled. Initially, the first one is set to true, and the second line is empty. You need to change the first one to false, and in the second line, right-click on the line, select Add, and add four sub-lines to it. In these sub-lines, you need to enter 1 (or 0 if you don't want specific creatures to appear in the recruitment. For example, 1 0 1 1 in a Knight dwelling will block the recruitment of Monks from that dwelling).

If you want the dwelling to depend on the player chosen at the start, select the random dwelling, press Space, and in Link To Player, select the desired player).
