I need a way of changing the header for only pages contained in one of the menu items. All other pages should continue to use the default header. Is there a good way of specifying an alternate to accomplish this? Some way of creating an alternate that is only used for content items under the specified menu item. Thank you.

Edit: We have built the header image into the theme and it displays on all pages. We need to override that only on pages that are part of a certain subset that will be constantly having new pages added to it. That's why I was thinking of targeting anything that is under the same menu item, but this may not actually work since the content items under that menu item have their own URLs and don't technically keep track of which menu item they are a part of.
