Wish for feature to make assets move on curved lines

I often miss a feature, where I can draw a curve on screen for an object to follow. It would be great to be able to create any shape and make the object follow the shape or curved line.

Right now, I have to tell an object the exact locations to go to in an animation. That starts to become complex, when I need the object to move in other ways than just a straight line from point A to B. I need my animations to be more dynamic, so a feature like that would help me a great deal.

All the best,
