How to write a sketch capable of controlling two different 8x64 LED matrices

Hello everybody,
I built myself a led screen having two 8x64 led matrices connected to many IC MAX7219.
I could obviously connect these two matrices with two Arduino modules, but my doubt is if it is possible to create a sketch (with the MD Parola library) capable of controlling both of them, each with an obviously different writing.
Has anyone ever thought about this possibility?
Thanks a lot!
