Substitution parameter from root

As an AF administrator, I want to configure templates with Point Creation using Substitution Parameters that can retrieve names and values from an element relative to the root element and working it's way down to the element wanted. A way for this to work, would be for the search mechanism to store the full path of the element and then work it's way down starting at the root. Currently substitution parameters can be used to retrieve information from elements relative to the element in which the substitution parameter is configured. Use case: I would use this template for elements that can be located at the third level or lower in the hierarchy. I need the element name of the element located at the second level of the hierarchy relative to the branch my element is located on.
