Although ti would not technically be part of the pivot table, you could
do this:

- Complete your pivot table (PT).
- Click on row 1, and insert a new row (or 2) to slide the PT down.
- Now, in row 1, use a vlookup formula to display the "Grand Total" at
the top of the sheet. e.g. =VLOOKUP("Grand Total",$A$6:$K$79,3,FALSE)
where a6:k79 in the range containing the PT, and 3 is the row of the
Grand Total I wish to display.
