Using Braille displays to show multiple items?

is it possible to have a 40 cell braille display (or multiple displays even) show two different things (like how a sighted person can have two windows next to each other). my thought is that if i have my uni assignment on one side and the reference material on the other, so that i'm not constantly changing windows back and forth.
I saw on apple support that you can make multiple braille displays show the same thing, but this isn't quite what i'm looking for.
thanks
