Normally in the Customize preview you are able to see only the pages that are linked.
With All Pages In Customize you will be able to see all the pages.
After activating All Pages In Customize, you will see the panel “All Pages” in Appearance => Custommize.
Expanding the panel “All pages” you have a dropdown list for each post type. Just select the single post or page you wish to see in the customize preview, and you will see it.
