row level security & overall sum

Hi,

 

I'm experimenting with Row Level Security.
In this power-bi-project we have different departments with their own budget.
I want to experiment with some roles (by department) and indeed i can see only the budgets of the departments i'v access to. All right!

 

But I want to see also the total budget of the whole company, but I only can see the total budget of the departments i'v access to. I can understand the result, but in this case i realy want the total budget of all the departments, even those i don't have access to.

I don't need to see all the details of the other departments, not even the budget of the other departments, but I need access to the sum of all the budgets!

 

How can I do this?

 

Thanks in advance.
