get value to the left in pivot table

[daniela5]

Is there a way to get the percentage of a value to its left in a pivot table?

For example, instead of the value 40 in Month May-22 i would like to show 54% instead ( % of 74) but the value 74 need to be shown as a full value of 74. Same with Jun-22, I would like to show 44% instead of 83 which is the percentage from 187.

Is this possible?
