I've looked through the documentation and the options, and there doesn't seem to be a general listing for elements of a slide that are named on the Selection Pane. There are ways to reference pre-existing placeholders from the Slide Master on a given slide, but no general listing for all elements that would fall under the Selection Pane, including those that may not be inserted into one of those placeholders.
It would be very useful for updating existing PowerPoints through this package to have one general listing that directly references each of the elements under the Selection Pane by name.
