Starting 1.20.2 theme update you can manage the links of properties and agents from theme options.
You cannot use special characters like “&”. After changing the url you may need to wait for a few minutes until wordpress changes all the urls. If the links do not change after a few minutes, save again Permalinks and it should be instantly updated.
You cannot change the structure of the URL to include different elements. This just re-names the existing labels with your own.
Save permalinks when you are done.
