IgnoreCollision in a specific PhysicsScene2D

(This question applies both to 3D and 2D physics, but my particular case is for 2D)

I have 2 Physics2DScenes running in 'parallel' (I'm manually calling Simulate), I am trying to ignore collisions between certain objects in a specific physics scene.

If I only had a single scene (the default physics scene), I could use the static Physics2D.IgnoreCollision, but that method is not available in PhysicsScene2D.

In fact, this can be framed as a more general question: How do I do all the things I would normally do with Physics2D on a specific PhysicsScene2D?

Is there are way to change the 'current physics scene' that the static calls in Physics2D act on?

 

Ok, I think I see how it works now. Most of the static methods in Physics2D take a collider as a parameter, and since a collider can only be in a single scene the functionality is not ambiguous. Where it would be (for example LineCast), another method has been added to PhysicsScene2D.

So my question doesn't actually make sense
I'll leave this here in case anyone else runs into similar confusion.
