Nested Thing Templates - Showing properties from things that share a grandparent template but not a parent template

Currently, I have a landing page that displays a list of things pulled from my grandparent template called ControllerThingTemplate via a service using a repeater widget. Inside the mashup of each repeated template is a button that navigates the user to another mashup to display more information about the current thing they are selecting. The issue that I am running across is that on the second mashup I need to display properties that are on the parent template that are not on the grandparent template. I would like to use one mashup for any these things. Is there a way to do this??
