Secondary services list?

Is it possible to create a secondary services icon list? I tried to use the ‘Types/Categories’ to differentiate services from to no avail. I’m not able to call a specific category of the service anywhere, am I? Would be nice to do so on the page I place the list. Ideas/Suggestions? Love this theme, thank you!!!
