Is this what you are after? I added the [Broad Category] field on the LoD shelf in your second graph, and edited your automatically generated action to work only using that interlinking field between the two visualizations. Bear in mind, that actions connect visualizations via fields that are in common. You can use all fields or only some of them to control the behavior.
Hope this helps,
