I would like to show both “author” (one or more) and “reviewed by” (just one person) for WordPress posts and pages on my website.

This would be for example a situation where an article is written by a content producer but the information has to be reviewed by an MD or other credentialed medical expert.

This type of functionality is in my opinion pretty much a must on YMYL (your money, your life) type websites.

My current understanding is that there is no way to do this in a way that would be native to WordPress and I should just use some sort of meta information plugin and add the reviewer as meta information on each page and post.
