Path follower using a timeline

I’m trying to animate a roller coaster that will follow a single path that contains multiple ups and downs and loops. Using a path follower it appears that I can only set a single ease on the animation. Is there a way to do this more like a timeline than a single tween? For example, if the roller coaster is going down a hill, then up a hill, I would use a inOut tween, but if it were going down a hill, up a hill, then down another hill I would want to ease in, then out, then back in and on and on. Is there a way to work a timeline into a path follower to get this effect, or a way to chain the easings across a single duration?

Path Follower must use only one tween, but you can give a custom easing function. Your function would choose an easing function based on the t range.

The other way is to use a timeline and an ordinary sprite and update the sprite’s position yourself.
