I'm trying to find a control that more clearly displays the hierarchy between the parent scenario file and the child runs for the Replicator widget. I found that you can configure groups for the ListView control but this is nothing more than a visual heading. There is no way to make the heading clickable or add buttons. I am trying a new layout that creates a separate ListView control for each group of scenario runs. I will make my own headers on the form above each of these controls with buttons to add or delete the runs. We'll see how it looks tomorrow.
