Hiding Writing Tools and AutoFill menu items

Hi,

I develop a 3D molecular editor, so the Writing Tools and AutoFill menu items don't make much sense. Is it possible to hide these menu items in my app? In the case of dictation and the character palette, I can do this:

  [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"NSDisabledDictationMenuItem"];
  [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"NSDisabledCharacterPaletteMenuItem"];

Is there some similar way to remove the Writing Tools and AutoFill menu items for apps in which they don't make sense?
