I am trying to be able to use my custom theme's full widith template. I set the custom-post type to 'pages' being checked, but when I go to enter a new post, it does not allow me to see the drop down to select my themes templates (I do have that available when I edit a page, but not when I edit my custom post type editing page).
How do I change theme templates for a custom post type of 'page'?
