expression A variable that represents a PivotField object.
The default value is 1 (Automatic). When the AutoSortCustomSubtotal property is set to 1 (Automatic), the data is sorted by the regular subtotals. The AutoSortCustomSubtotal property can have one of the index values listed in the following table.
Sorting is supported only by custom subtotals that are actually displayed in the PivotTable, so trying to set AutoSortCustomSubtotal to a value representing a custom subtotal not in the PivotTable view will return a run-time error.
If sorting is applied based on a custom subtotal, and that subtotal is removed from the PivotTable, the AutoSortCustomSubtotal property will automatically be set to the default value (1).
