Using ellipses
A single period can be used, like ellipses, in place of object names, as long as that object name can be interpreted as a unique object.
For example, if you have the following object name:
City Field:BillTo Customer:Account:File
you can replace it with
City Field:.:File
If file also contains another City Field, such as
City Field:ShipTo Customer:Account:File
and you use the Use Ellipses option, the system returns
City Field:BillTo Customer:.:File
