Allow Pivot Table (2 Dimensional) view for Subrelations and Correlation reports

While subrelations allows you to breakdown several line items by using the icon near the variable name instead of values, the resulting view is a 'ungrouped' kind of view and not a two-dimensional pivot kind of view. The ugrouped view is useful if you want to see multiple success events but the pivot table view is much more intuitive and insightful if only one success event is selected.
