[opensuse] Rearraging the Kmenu

Is there a way that I can manually rearrage programs in the Kmenu, for some reason programs are not being put under the right category, or they are in more than one. For example Supertuxcart, which is an arcade game, is under Kmenu > Games > Arcade and Kmenu > Graphics. I know that a game should not go under the Graphics category. Thank you in advance
