Is there a way to add calculated row in the pivot table (OTBI Analysis)

Content (required):

I am trying to create an analysis like below using pivot table functionality in OTBI analysis. In this I want to add a row. Values of the columns in these rows are calculated based on other rows of the pivot table.

Is there any way to add a calculated row like this? I tried using Create Group but I cannot write formula there...
