Is there any way to have a specific, single header image be used on a page?

On one of my ATA sites I have three header images which rotate as you navigate around the site. On another site we have a single header image used on all pages, posts, etc.

I've just discovered the WP "Featured Image" option and would like to have the header on some pages be different than the standard jpg pre-loaded as header images. Is there some way to enable the Featured Image function in ATA?

The featured image does work but it is for showing thumbnails in excerpts and not as a banner image. What I have used in the past for what you are doing is the Dynamic Headers plugin. It hasn't been updated in a few months but I think it still works fine.
