Assigning a nurse to a ward (like janitors in services DLC)

I like to put one nurse station for my HDC and one for my regular ward so it would be great if we could assign a nurse to a ward and like the janitor this ward would be priority. And it shouldn't be too disruptive to the logic of the game, since this system already exists.

I would also like this, and with doctors, so they will look after a particular ward.

Moreover, i would like it to be possible to appoint which particular restroom or toilet the patients and doctors will go to, otherwise they sometimes run away to another department or to another floor

Lets not assign workers to rooms. Lets just assign rooms to rooms with all employees or patients in it
