Have Osu! overwrite Previous Inherited Sections when using [Add Inherited Section]. It's a real pain in the butt to have to go into timing setup every time you need to tweak an Inherited Section, especially when working with mass Inherit Section Changes (you use a different sample set, for instance). This would also fix an annoying quirk in Osu! where it stores two Inherited Sections at the same point and randomly picks one of them.
