Waterslide mover - Prefab Shapes?

Its really difficult to get an actual waterslide looking slide, I feel like if we had a few prefabs that pre-add the spline into it for us it would be a lot more practical, I did attempt using elbow canvas here but getting a spline to line up inside wont be very possible.

Something Like this is what we need, (Press a button that says Add Shape - Adds it to the end of the last spline point)

Are you working on a waterpark map in the future? I’m in :sweat_drops: :sun_with_face:
