After properties are synced on your WordPress site, you can modify slug to give any property a iconic url.
A property named “3 bedroom beach side villa” will produce a url like example.com/3-bedroom-beach-side-villa . You can modify the slug to give it a url like – example.com/awesome-beach-villa.
If you need to make above changes, just make sure the “Property Slug” option is disabled. This will make sure any future sync won’t modify the slug.

Besides that, also make sure Slug Source is set to none.
