Making "gaps" in the generated spline mesh

[VoltDriver]

Greetings!

I have a setup, using Curvy 8, where I am generating a racetrack for a game I am making. I would like to make gaps in the racetrack, to represent jumps.

I would like to know if it is possible, and if so how, to define on my single spline points where the mesh won't be generated.

Essentially this:


So visually, it looks like there is a hole in the track. This is represented by a hole in the mesh and collider.
But, the spline stays complete.

Is that possible?

Thanks!
