Directory: Can I link taxonomy titles?

Hi,

I am using the directory plugin. When I click on a category, for example "Communication" > listed under 'By Subject Area', the subcategories show. The header then reads: By Subject Area /
Communication (and then the subcategories are listed). Here is the page: http://manag.rs/oN0cSr

Intuitively, I want to click on 'By Subject Area' to go back instead of using my browser's back button. Do you know if it is possible to hyperlink 'By Subject Area'? Thanks for your help.
