Header image specific per page not one for all?

I’d like to have one specific header image per page not one common image that shows on all pages. In Customizing, header area, header media I can add many images to randomize, but I want one specific, different, image to show per page. I have a large featured image per page now, but they do not override the header area image.

The page I need help with: [log in to see the link]
