I would like to see a new starting point added to the navigation asset. self. (i.e. its own url) The reason is to dynamically change the start url of the nav asset, for when a nav asset is being used inside a Package. To achieve a dynamic 'TOC package'.
A start point modifier would probably be necessary as well.
Calling the starting point, 'relative to navigation asset' would cause less confusion than calling it self.
