Not in the Analysis grand total row.
But you can make your own grand total calc.
SOME times you can even force your calc value into the grand total cell, but I always handle it by making a second sheet that dust displays my grand totals (when I want something other than what Analysis does by default) and position the second sheet on a dashboard next to (or below) my actual data sheet, and as far as the user is concerned it all looks like one visualization.
So here is my recommendation: Hack up an anonymized version of your workbook. Strip it down so that we don't have non-essential stuff cluttering things. I'll work with you to get the grand total you need.
