Similar to what is already possible in the rooms, you can now use the URL placeholders in the custom areas added to the navigation bar.
When adding a custom area, the URL field is now allowing the same placeholders as the rooms:

The available placeholders are:
"__FIRST_NAME__" - First name of the user accessing the page
"__LAST_NAME__" - Last name of the user accessing the page
"__IS_HOST__" - Will have 1 if the user is host in the event and 0 if not host
"__UID__" - Unique id for this user
