Capture heatmap screenshot without data

I have a page where I render my content using canvas, which is not supported by the heatmap module. So for the screenshot URL I use the same page where I render the content using images (which is slower and has worse resolution, so I only use it for heatmap screenshots, users don’t access that page).
When I create a new heatmap, is there a way to automatically capture the screenshot from the other page? Or do I have to make the user who created the page/heatmap visit the page in order for the screenshot to be captured? And if so, is there a way to exclude him from the tracking, and ONLY capture the screenshot? Thanks!

Hi Marek,

The plugin allows you to specify and alternate URL to capture the screenshot, is this what you are after?
