After selecting data and filters to narrow it down, the user is taken to a 2nd level of the navigation where he is presented with content displayed in a table like in the following image:
Each row links to a 3rd level of navigation that displays the expanded results. Each row links to its own set of results (e.g. "Type A", "Type B", etc.). However, you can click on the title of each section to access a 3rd level of navigation that contains ALL the expanded results (regardless of their "type").
I am looking for a way to have the user intuitively know that the section title is, in fact, a link (and a very important one).
I would like to avoid adding new elements (arrows, icons, and so on), wait for a user action to indicate it (tooltips) or change too much of the current styling.
