Is there a way to add items to the page selector dropdown (see screenshot) in the theme editor? Other than adding a new page through Online Store > Pages, of course.
I'm trying to emulate nested collections similar to this post. But instead of using linklists and managing sub-collections through a menu, I want to manage sub-collections using the theme editor. I have the templates and sections already working the way I want to. The last key to a better UX for my client is to be able to add the parent collection (she only needs one) template to the page selector.
