Powerpivot excel pivot-tables with multiple rows (problem expand / collapse)

Hello, 

I made a pivot table with powerpivot so I get kind of data: 
The problem I have is that when I reduced the city of Bordeaux for example, given this city are reduced both that really interests me as the other non-company (all cities Bordeaux are reduced). 

I would like to know how to get it is there that the city which interests me is reduced?
