Property Groups allow multiple properties to share roles. This feature greatly simplifies setting up user roles at the individual properties.
To create a property group:
1.   Click 
 
 Administration on the Shortcuts 
 bar to display the Administration form.
2.   On the Properties & 
 Roles tab, click 
. 
 The Property Group form appears.

3. Enter a Group Name and click OK.
You should rename and delete property groups only during the configuration process. You can only delete a property group if it is empty: delete any properties within the property group first.
