I have a pivot table with depts on the rows for 3 separate years and the months in the columns. I have the percent difference for each month in columns and they are showing for each dept compared to the year before but I was wondering if it was possible to only show the percent difference from the previous year's total and not show each dept difference.

eg.
DEPT JAN JAN%
abc1 26 52.94%
abc2 4 34.00%
abc3 10 23.55%
Total 40 23.16%

I don't want to show the % for each dept but only show it on the total at the bottom. Is this possible?
