Distinct count subtotal

Hello all 

Please see my data v-frfei-msft amitchandak 

I have highlighted in my power pivot the column data required and the current measure being used. The measure shows the value 1 against any sales person who has completed a review , this has been achieved by filtering for a distinct count of any value above zero and displaying how many of these values exist in each row, so any number that is not 0 in any row will return 1. 

I would like to subtotal this for each column so that the measure for the sales people group should show 2 as there are 2 people in this group that performed a number of reviews rather than zero. The column  highlighted in green represents the results i wish to see
