Editing Camera Rig Rail to follow BP Spline

Hello,

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?

Wondering the same? Perhaps kicking this back up to the top will do it. Did you ever find a way?
