1. Add new page

4. Configure own way in the "General" tab and then set default value
5. Since now the page will display only Chicago listings
6. You can further edit this page fully via page builder
7. You can redirect old auto generated link to this page. The fastest way will be to install Simple 301 Redirects plugin: https://wordpress.org/plugins/simple-301-redirects/ . It allows to change any url that is part of your domain to the new location. 301 redirect is preferable for both users and search engines. We use it also on our own projects.
