It could be useful to instruct the hospital to only accept diagnosis patients in certain psychiatries and wards, and likewise for treatments.
I try and split diagnosis and treatment to completely different parts of the hospital. So I would rather not have undiagnosed people in the ward next to operating theatres.
Until you get late in the game and have to deal with Alien DNA researchers are pointless having out of the research dept.
So I would like to see something in place that a researcher can leave the research dept to deal with Aliens before returning to do research. That was a total pain when I found out they needed the a researcher to cure them. (I normally have a lot a Surgeon Psychiatrists running around).
