Camera problems

There seems to be no way to set the camera that is used instantly and there also seems to be no way to reference the actual camera for it instead of a actor.

There seems to be only this bad node and settings time to 0 is not instant:

Then there are these nodes that require a player controller instead of camera as the input:

But as mentioned I can not set the camera instant to workaround that I can not use a camera as a input instead of the player controller.

Are those nodes just dumb or am I missing something?
