I have a prefab called "BoeingPrefab". It contains a model of a Boeing 737 and a script and some other stuff. I want to make a similar prefab, but then with a different airplane, a Cessna 172. So I copy the prefab (prefab variants like in Unity do not seem to exist, at least according to the Lens Studio AI). I rename the copied prefab to "CessnaPrefab", and replace the airplane model in it. Now whatever I do, where ever I rename "BoeingPrefab" to "CessnaPrefab", as soon as I drag it into the scene it is called BoeingPrefab again in the scene. The only way I have been able to kick Lens Studio into doing what I want (and expect), is opening the CessnaPrefab.prefab file in a text editor, look for the text "BoeingPrefab" and change it into "CessnaPrefab".
