Is it possible to create a metafield that is limited to a specific page only?

I want to create a metafield called “home_page_banner” and have it appear only in the editor for the homepage.

While I can use a namespace to limit the metafield display only on homepage but what I want is to make it only appears in the metafield editor for the homepage to avoid confusion.

For example, if I have two metafields called “home_page_banner” and “foo_page_banner”

I only want the “home_page_banner” metafield to be visible in the editor for the homepage and so on
