Separating Categories?

Site can be seen at LHSSports.net.

On my site I want to display two “Category” widgets. One for “Sports” and one for “Other Extracurriculars.” So much as actually getting the headers up was as simple as just dragging and naming two widgets to the displayed sidebar. The problem arises in the fact that both “Category” widgets display the same categories. Is there a way to separate the categories shown under each widget heading?

For example: The heading “Sports” shows the categories “Band,” “Baseball,” etc…and the heading “Other Extracurriculars” shows those same categories. Is there a way that I can keep the “Sports” heading showing the same categories, but then change the “Other Extracurriculars” heading to show categories such as “Drama,” “Journalism,” etc…?

Any help is appreciated.
