Personally, I haven’t really found a way to connect rooms above rooms in a way that uses the ladder position I actually want. Its just random, which is annoying because most of the time it doesn’t give me a single ladder that connects all the floors, it connects 2 or 3 at one spot, another 2 at another, etc. It’s fucking dumb. I mean, I could use the single room pieces for this, but that looks ugly and is otherwise totally unnecessary.
