This would potentially require multiple credits per render,

But the ability to create multiple "pages" / "canvases" per template (Canvas, HTML) would be an interesting feature addition.

The rendered output would then either return a single PDF file with multiple pages, or URLs to multiple rendered images.

Each "canvas" in the template would support variables dimensions (8.5x11, 11x8.5)

Variables passed would apply to all template canvases (pass business_name once, and all instances are adjusted)

Similar to how a Google Presentation supports dynamic {{merge_fields}}

(I guess we could just use Google Presentations - but RenderForm is cool too)
