How do I customize the url of a page or post?

The Permalink Manager allows you to customize a page's URL or add redirects to or from the page. Access the Permalink Manager in the "Permalink Manager" panel within the block editor settings sidebar from a page or post's edit screen as shown below.

The "Current URI" field sets the path of the page/post. This is the part at the end of your site's URL: yoursite.charlotte.edu/[current-uri-here].
