How to swap objects for prefabs?

Hi Everybody!

Quick question here:

In cases where I have multiples of the same object (trashcans, for example) I would like to swap them for a prefab (which we should have used in the first place, but when we started we weren’t thinking straight, that’s changed for future levels…)

Is there a quick way to swap all copies of an object in a level for a prefab, or will I need to manually switch them out one by one?

To my knowledge there is no built-in way to do that. However, i think it should be possible to write a simple editor script which would do that for you.
