Adding a new Totals Column

Hello!
I've been googling and playing around with my PivotChart, but I can't seem to add a Grand total column to the end of my chart.
I need it to total each row, as well as the bottom grand totals, all on the right side of the chart.

I considered simply adding a column with the sum function, but I need to it to actually be a part of the table.


Thank you!

Jess
