I am struggling to change my website's URL structure after an agency set up the layout and all backend coding. The agency set up two additional tabs on the wpengine side bar that act like the pages tab. These are labeled 'products' (B2C) and 'solutions' (B2B) and are programmed so that any page that is created in these tabs will start with a URL slug of '/products/' or '/solutions/'. What I am trying to do is change this so that the slug will be '/individuals/' and '/businesses/', but cannot for the life of me figure out where to change it. I've looked through everything on wpengine, even looking into the php code. I tried updating the php code, but was flagged with an error message saying I need to try an SFTP way to change it. Does anyone have any suggestions on how I can change this without breaking/rebuilding my website?

I doubt any one here can help – you will likely need a web developer, with access to your WP admin.
