Matrox Resolume and multiple display query

Is it possible to project separately mapped 'slices' through the triple head or will it always use it's three outputs as one large screen??

I need to map three screens individually through the same output but have control over the screens content separately.

Racking my brains trying to figure it out before I buy one for a gig I need three separate outputs for on sat (I only have two on my mac) any help would be amazing. Cheers , p
