Have a button appear based on Slicer Selection

I have a page with a slicer allowing users to toggle between four categories, and it changes the visuals on the page based on selection.

One of the categories has a breakdown underneath it of three sub-categories. I am showing the breakdown of sub-categories on a different page. I have a button on the main page saying 'show breakdown' but I only want it to appear when users have selected the category which has the breakdown. 

Is this possible?
