So with the release of the Donjons, I feel they are quite similar to Krepost where they are defensive buildings that can train their unique units, and I want to bind them to the same keys, since you would never end up owning both buildings at the same time in normal gameplay.
But it seems that is not possible, which is a big disappointment really. It becomes annoying when I have to remember more and more keybindings for all the different buildings, especially if you add more new buildings unique to a civ, and you can’t bind it to the same key as the unique building for another civ.
So I suggest making this possible for these kinds of buildings where you most probably won’t get a scenario where you own both buildings at the same time.
