Matrix view. Display records with no data for specific level of hierarchy

Hello everyone. Check out my puzzle 🙂

Input:

I have a structure of sales managers with 3 levels of hierarhy. Regional director->District director->Emlpoyee. Let's call this table 'Users'

I can easely build a hierarchy for them wich looks like

1. Mask
   1. John
      1. Petr
   2. Ipek
      1. Fedor
      2. Yan
      3. Paul

I have another table with sales of those employee. Let's call it 'Facts'. Here it is.

It is obvious that those two tables linked via Employee column.

Let's say I have a dash with matrix structure and date slycer.

The matrix has been updated with 2 more levels of hierahy.

Director->Manager->Emlpoyee->Client->Price

From the box, the matrix in pbi will show data with Employees who sold something. Like this.

1. Mask
   1. Ipek
      1. Yan
         1. it0301
            1.  6$
         2.  it0984
            1. 789$
         3. it020393
            1. 2$
      2. Paul
         1. it5432
            1. 12$
         2. it04211
            1. 6$

We do not see nor Petr nor Fedor in the matrix because they did not sell anything.

The problem is - Business whant to see all the hierarchy of sales managers including those who did not sell anything during the period in slycer (or in 'fact' table). 

This could be solved via feature 'show values without data'. But in that case each Empliyee in matrix will have list of ALL clients and all deals from the 'fact' table. Despite the fact that it is not readable, it makes the model very slow.

Any ideas how to fix/freez the hierarchy on a specific level and do not show records w/o data for lower levels?

Thank you in advnce.
