Community Tutorial: Follow a Spline and Report Distance Along It Using an Actor Component

Is there a way to take control of the spline animation via sequencer? Perhaps keyframe spline percentage? I looked at the chaos drive example where the car is pushed through take recorder. That is great for capturing dynamics on top of spline animation. If dynamics are not required and I want to keep the splines live for flexibility, can I directly control advancement along the spline via sequencer? Thanks!
