Problem:
The user would like to preview a content template with a different post that the 5 posts on the preview selection dropdown.
Solution:
The preview selection dropdown is also a search box, just start typing the title of the post and it will appear. It is limited to 5 posts, you will need to have distinctive names to match the search. This will work for draft posts too.
Problem:
Site audit error: WPV-pages have no self-referencing hreflang
Solution:
However, irrespective of what tool/plugin you are using, the thing is that the pages reported as missing the self-referencing hreflang links are search results and paginated View results.
As such, they are not necessarily equivalent to a similar page in the other language anyway, and it may not be appropriate to add hreflang links on such pages. (A similar search in different languages may produce different results.)
