Asking for "multiple multi docks" is a different question from "can I arrange multiple windows on my screen"
Now you have discovered this you MUST get your head around SCREEN SETS
You can set everything up how you want for "tracking" / recording and save it as a screen set. You can then layout everything how you want it for mixing and save a mixing screen set - rinse and repeat - then you can toggle between the views using the screen set number buttons
I haven't tried on multiple monitors but I am sure it is worth a try
