Category view with K2 content

Hello everyone, If you visit:

http://www.brigittegiguerecourtiere.com ... ory&id=112

You'll notice a category page with the first two links Service a la clientele and Sujets delicats, which are sub-categories. The other links are items. Is there a way to change the position of the sub-categories to the bottom rather than the top, meaning that the links Service a la clientele and Sujets delicatswould be at the bottom of the listing rather than the top. Thanks in advance for your help. Best regards.
