Disable rendering but keep nodes

Good morning everyone,

Is there a way to disable rendering of the scene the easy/hassle free way, but still make the animation using one of the rendered frame AND the compositor nodes. I.e. Render 10 sec of only the compositor effects. Now I know you can add an image texture and then render that instead of the scene, but you have to change your node setup, then go back to the previous node setup and so on. My question is: Is there a button to do such a thing?
