well, i didn t find any mention of that in g70 or e60 manual, but i might have passed it by mistake.
anyway, i had the impression that this morphing function not only let you combine different parts of different styles into a new one, but gives you intermediate stages between two parts of a style...
something like not only A part, or B part for a new style, but rather A ----->B several possible combination.

maybe i am criptic, or at least my english does not help me enough.

still, i am not sure there is morphing on g70 or e60/80.
