How do you create a few elevators that reaches all departments on each level?

[Mrs. Lemongrass]

I have had to create an elevator for each department and it's so exhausting. It messes up the design plan. How do you connect the elevators to all floors and every department?

I know how to put a elevator on the map, but I have to put multiple elevators for each department. Is there a mod ?

??? just make a good floor plan. my newest hospital has 6 hospitals and none of them cause any issues with design.

I don't understand the problem. Elevators are independent from departments, you just place elevator/elevators wherever you need, and then mace corridors so every person from each room can reach them. After you add new floor all existing elevators connect to it automatically.
However having a single elevator for a huge hospital is a bad idea. Generally the more the better, so people who need the room just above them don't have to go to the elevator in the opposite side of the building and then go back but on other floor.
