Move Site Categories option to generel settings tab


I really want the blog site category option to be in the general settings tab, to make it easier for our users to find and change category. Right now the "Site category" has it own menu tab in the blog setup, but to make it easier for the users, we want to place it right under the existing settings in "General" (or "Generelt", as on the image).

Our general settings is already customized, so it only shows the most important settings for our users. I have tried to show on the image what i want to accomplish. Notice that I am using a wordpress admin theme.
