Projection Mapping with 2 projectors & DualHead2Go

I went on a Guerrilla mapping yesterday and had some trouble setting up my projectors to correctly detect as a single tall display.

Essentially, I needed Windows to detect both projectors as a single tall display. I had setup this mapping as a wide spanned single display and i had difficulty aligning correctly.

My question - Is there a way to simply have windows detect both projectors a single tall display to use in Touch Designer? or is there a workaround i can use in Touch designer using Kantan mapper?

Here you’ll notice that my edit window in Kantan mapper.
