Is there any way to add sub categories under category in Service Operation Workspace?

Is there any way to add category under another category is Service Operation Workspace ?

 

For example incidents(Main category) -> Management (Sub category) -->> UX Lists (e.g unassigned, operational activity)

Right now each Category has its own UX Lists.
