How do I add a page header to the fundraiser page?

I would like to add a page header to each fundraiser's page. Currently, I am using the Salient theme for my website. With this theme, when I create a post, I am able to configure the post header at the bottom of each page, but unfortunately this option is not available on the fundraiser page.

Take a look at the screenshots attached. The Fundraiser_page.png attachment shows the entire page on a fundraiser page, which is missing the post header settings options. The Blog_post.png attachment shows a standard blog page which has the post header settings available.

Please advise.
