Can I change splines directly on runner controller via script?

[sikamaru]

I am an artist developing maps with the Spline tool and rather than trying to finish the route in order to get the next one, I want to go over every route quickly by just teleporting to other routes via the UI button.

I already made a script to create a list of all the splines in the game, and I want to directly input different splines into the Runner Controller / General / Spline slot in the inspector.
