Can you change guitar score to using the usual key in guitar music notation with an octave key?

Guitar music is usually noted one octave above the "real" pitch in so called Octave-Clef. This is shown with a small 8 attached to the bottom curl of the G-key. Garageband uses the standardl G-key, and F-key or the split G and F keys for high and low notes as e.g. used for piano. So creating a guitar track in music score is rather tiresome for guitarists. Have I missed an option to change the notation to using this key? If not adding this key would no doubt greatly help the many guitarists using this great musicians tool.
