more than one LCD display in one system?

[painfree]

Is it possible to put more than one 3.5" Display in a system?
And if so, may I be able to address them separately?

I just bought on the 3.5" display and would love to add another one or two of them to my system.

The software only allows one per type, so you can have only one 3.5'' but you could add a 2.8'' too if you want, but not two 3.5'' or two 2.8''
