Show Specific URL in Folder in Pages Overview


i have some URL’s /parkklinik-heiligenfeld/xxx and one URL /parkklinik-heiligenfeld
Is it somehow possible to show the /parkklinik-heiligenfeld URL in the Folder /parkklinik-heiligenfeld/ ?

here is it how it actually looks?

the site is configured without a slash at the end of the URL’s.
I want it wihtout changing this.

I tried adding a slash with _paq.push([‘setCustomUrl’, location.href.toLowerCase() + ‘/’]);
But it seems not to work
