When testing an item using configuration based test I find that I would prefer more Hierarchy on the report but not any additional VIs.
I Like the use of call chain but i think its a bit inflexible for some situations.
I imagine the implementation would be somewhat like this:
I think i would consider using a String Array as apposed to a string shown above to add additional false nodes to the call chain. (These call chains are scattered here and there).
These would have to be passed into the assert nodes otherwise they would have their default behavior.
