Exporting UX template to HTML, cropped?
 

I'm using Michael Angeles' UX template, and am creating clickable HTML prototypes using the Wireframe canvas layout. The canvas is landscape format, and the web page area occupies the left half, with the rest taken up by notes.

What I'd like to do, when exporting, is to crop off the right-hand half of the canvas, giving me a portrait format result centered on the web page. Can I do this using the Canvas Size Inspector? I'd like to avoid having two versions of my wireframes, one for prototyping and one for printing.
