To add subtotals based on multiple columns, as shown in Figure 1,
sort the dataset by the desired columns and then apply the subtotals,
making sure Replace Current Subtotals is not selected. The subtotals
should be applied in order of greatest to least. For example, if the
data is sorted by Region, with the products within each region sorted,
apply the subtotal to the Region column and then the Product column.
