Quick prefab update

What are alternative ways of updating prefab from scene,
that are not drag and drop.
Maybe there are some editor scripts that add simple “Update the original prefab” button?
Or any other easy fast way i don’t know about?

Once you drag and drop any scene object to a prefab folder,any changes you made to the scene object can be saved to the prefab by selecting the object’s root in scene/hierarchy then

Goto GameObject>Apply Changes To Prefab

Note : Any changes you made to the object in scene will be showed as bold in inspector.Once you apply changes to prefab,Bold letters will become normal.(Bold text in inspector indicates unsaved changes to prefab)
