If you tell us exactly what you want to do then maybe we can help. I worked with unreal engine for many years, most of those years in games. Being unable to set the pivot point in unreal seems a bit of a bummer but there are easy ways to work around this. - You know you can attach objects to other objects. So you could place an invisible sphere, attach the object you want to rotate and then rotate the sphere. Let’s say there is a door, you attach the door to the invisible sphere where the hinges are. Then you attach the door handles to the door and they can be rotated by their own pivot while you open the door. Thousands of game scenes have been made with sometimes lots of objects rotating or moving around and there was no pivot you could have adjusted in unreal. You just need to be creative with what you can do.
