I want to move my page-slug.php files to a subdirectory and WordPress should recognize them automatically. How could I achieve that? (Unfortunately this did not help me - and this link mentions template-parts/page, which does also not work)

I want to move page template files like page-{slug}.php to a sub-directory within my theme, in a way that WordPress will recognize them automatically. If the page templates of the said form doesn't exist within the sub-directory, then WordPress should fall back to the default template loading rules. How can I achieve that?

Note-1: This question and corresponding answers are more generic for page templates and this link mentions template-parts/page, which is not the same thing.

Note-2: I have multiple page-{slug}.php like page template files, so I want to move them to sub-directory for a more tidy file organization.
