Record Inspection Results Fiori App - How to add unplanned characteristics

We are working on enhancing the Record Inspection Results app to allow the addition of unplanned characteristics to the results recording screen. In working with the developer we noticed that there is an AddCharacteristics view available in the app, but we do not know how to call it.

Can the AddCharacteristics.view.xml file be called from the app? And if so, how?
