Present different level of hierarchy according to a slicer

Hello everyone,

I have the following data:

Destination:

• LATAM (h1)
  • Region1(h2)
    • Country1(h3)
    • Country2(h3)
  • Region2(h2)
    • Country5(h3)
    • Country4(h3)
• ASIA (h1)
  • Region3(h2)
    • Country6(h3)
    • Country7(h3)
  • Region4(h2)
    • Country8(h3)
    • Country9(h3)

With the destination hierarchy presented above (which only Highest level of the hierarchy is in a slicer -h1-), I have a Matrix with destination on columns.

Basically, I need that when nothing is selected on the slicer, only h1 level is presented. But when any item on that slicer is selected, only h2 level is presented on the columns on that same matrix.

I think this is done using a calculated column but I'm not quite sure, I'm a PowerBi amateur!

In advance, thanks for any help!

David
