I often use subtotals in mega tables/pivot tables to group child rows together, regardless if I'm aggregating totals or not. I've found that being able to suppress the subtotal label text (e.g., "TOTAL") would make the tables look much cleaner.
I don't see a way to complete omit the label so I usually put some small character in the property, but it still looks a little cluttered.
It would be great to have an option to omit the label altogether and just show the value of the column being grouped in the subtotal without any label.
