Option to allow offsets to keyframed animation.

I know this can be done by parenting an object to a dummy but that is a messy method.

If an object has movement, rotation or scale keyframed animation it would be great to have an option so that moving, rotating or scaling an object would keep the keyframed animation but just offset it.

eg. A moving object could have the entire animation relocated just by moving it or orientation of the animation path by rotating it to a different angle.
