I see what your problem is in that situation.
I’d suggest a bit of PHP that’ll change the user’s role. See: https://s2member.com/kb-article/rolescapabilities-via-php/
You’ll need a PHP execution plugin for PHP to work in a post/page’s body.
You can add the role-changing code to a page where the user lands when he clicks on a link to modify his account’s level.
I hope that helps. 🙂
