Force every prefab to be the same for every scene

Let's say I have a project with 50 scenes. Those 50 scenes (scene #1, scene #2... to scene #50) all contain a complex Prefab, called CommonPrefab. I wish to have the same 50 prefab in all 50 scenes. So I drag it in. All good so far. I make a change in the prefab in #2 and click Apply, all good. Later on, in scene #4, I make a change in CommonPrefab, but forgot to apply it. Then in scene #5 I make a change in CommonPrefab (changing the same inspector fields as in scene #4 but with different values) and click Apply. Now scene #4 and #5's CommonPrefab is slightly different from one another. How do I make it so I can easily and safely ensure all "CommonPrefab" instances are the same? Apologies if my question did not make sense, I can elaborate or reword if needed.
