Force Users to Always Submit Post Changes for Review

Hello! I’m working on a business directory section for a clients website, where we’re using separate posts to allow a business to list their own information.

My initial plan was to use the Contributor role (Or a custom role) to limit a businesses access to only their post. Then we would only ever allow the business to submit their changes for review, not actually publish their changes themselves without being approved.

Unfortunately, it appears that such functionality isn’t built into WP by default. After an Admin publishes a pending post, it then allows the user to freely publish changes to that post in the future without approval.

I understand that the original intention for the Submit for Review option was for more of a traditional blog setup, where a person would submit a post, have it reviewed, then move onto making a new post, and ever really touch any of the older ones.

Would something like I’ve envisioned be possible? Is it something that could be done without any plugins? If not, are there any plugins that would achieve such functionality, or some edits I could do to my functions.php file?

If I haven’t made my idea clear, just let me know, and I’ll do my best to rephrase it. Thanks!
