Editing Camera Rig Rail to follow BP Spline


I am putting together a car rig system that doesn’t utilize the chaos vehicle movement BP. Instead I want to put together a system where I have my car parented with the camera rig rail so I can scrub and keyframe the position in the sequencer. I have BP of a road created by splines.

Is it possible to edit the camera rig rail in a way where I can use the BP road’s spline as the guided path for the camera rig rail?
