You can define what level you want to show, though it depends on what dimensions you have in the pivot table
you can do this either by using total, this depends on the dimensions or aggr which creates a temp table

You can do that with a conditional expression in your measure.
Lets say you have a pivot table with 2 dimensions on the rows and 1 dimension on the columns.
If the highest level (1st) is company and the 2nd level is employee than you can change the measure for the 1st and 2nd dimension using the dimensionality() function:
In this case Dimensionality()=1 refers to cells calculated at the Company level and Dimesionality()=2 refers to cells calculated at the Employee level
So your measure can be
if( Dimensionality()=2 , <expression for employees>, <expression for all other levels including grand totals> )
