make sidebar.php editable in admin area under "pages"

In the admin area of WordPress, I go under the “pages” section and I can see and edit all of the pages that I have created.

I also want to have the sidebar.php page to show up under my “pages” section.

Currently, I have to go into the “editor” section to edit sidebar.php

Is there a way to achieve this?

Thanks.
