Cell Quality

[Rex Dart: Eskimo Spy]

So like a lot of people I have a pretty big prison already I wanna keep going with as alpha 33 came out. In other words, I have a ton of prisoners in cells all over wanting different qualities. This is a big pain in the butt. So I'm thinking, what if I upgrade whole cell blocks to be quality 2, 3, 4 etc? Will more guards transfer prisoners around to appropriate qualities or will the quality 1 prisoner whose cell block I upgraded to quality 3 still get that cell?

Let me try to explain that alternately in case that wasn't clear.

-Hypothetical prisoner is worthy of quality 1
-I upgrade his entire cell block to quality 3 and leave another entire block at quality 1
-Will this prisoner stay in his sweet cell or will the guards move him to what's proper for him?
-Does anyone know what the tolerance for any of this quality stuff and guards putting prisoners in cells is?
