Say, for example, I have a head nodding animation that goes: +5deg, -5deg, +5deg, -5deg etc etc... But then I decide I want to offset the whole of that tilting by a few degrees so to something like +7deg, -3deg, +7deg, -3deg etc etc. So the whole animation is offset by 2 degrees but the relation between the +/- amounts is the same. Is that possible?
