Is it good to specify what Actions of the Input Manager do on several Scripts?

You can specify what an Action of the Input System does with lines like: controls.CustomActionMap.CustomAction.performed += ctx => /* whatever you want to do */;
in the Awake()-Method.
Can you do that in multiple scripts or should you do all this in one script? Does this influence performance?

Thank you for answering!

Can be in multiple scripts.
The difference in performance is small.
However, it’s better to do everything in one script because the craving in the code is and you don’t have to look for several different codes.
