Correct Solution:

1. Create Property on in Document Types which applies to all pages you want to change the URL
2. Call the name anything you want e.g Page URL and Possibly give it a new tab.
3. Call the alias umbracoUrlName
4. Type as text sting
5. Should not be Mandatory (As when you start replacing .Url with .umbracoUrlAlias within the views it will need to be present)
6. Tab as Generic
7. Click Save on top right on the page
