Mega Table Subtotals: Need more flexibility
On Mega Tables, you can only subtotal by the left-most column. However, sometimes there are sub-categories within that larger parent category that also need to be subtotaled.
Please add the ability to subtotal by further depth. In the image below, I want to be able to sort the whole table by my first column, closing date, but really want to be able to subtotal then by my second column, Market + Show. Red lines indicate where I want to see further subtotals.
