Display common values for selection criteria

Hello everyone,

I'm having the following dataset.

I'd like to select Benefits and get Impacts that are associated to all Benefits that I selected.

Example: if I select Benefit 1 and Benefit 3, I should see only Impact A and C.

At the moment I'm getting all Impacts associated with Benefit 1 and Benefit 3 (exmple attatched).

How can I do it?

Thanks in advance!
