Please add the ability to set an existing page as the "parent" without having to create a redundant folder with the same slug.

I assume that for most people's purposes, if they are organizing pages inside a parent subdirectory, they will want to also have a page associated with /parent, not nothing.

That said, why should we need to create a folder /parent AND a page /parent to create the hierarchy /parent/child where /parent is also a page?

Creating a page is creating a folder anyways, so please make it possible to set pages as parent folders.

Thank you!
