Multiple Projection Nodes | Automatic select rendered Camera

[maxtervfx]

Right now I'm working on a project in which I create toon shaders with texture projections. Until now I did one shader that already has 3 projections and there will be much more. So in the end I have a huge amount of projection nodes in which I have to pick the main camera for each node. This would get really frustating when I chose to use a different camera.
So my question is, how can I link every node with the one camera that is currently rendered by Arnold. Would that be possible with the relationshop editor?

So a fellow student wrote a python script in which I can write down all projection nodes and one render cam.

Buuuuut I noticed that when I don't select any camera in the projection node at all, it automatically selects the current render camera. 😂
