[Editor Feature Request] Component Editor with Viewport

Let say, you have a Component that has many child Components and want to add to several Actors.
Currently, you will have to recreate the Component hierarchy to all Actors.
It would be simple if you can reuse the parent Component but you cannot.

Right now, Component Editor is missing “Viewport” so you cannot really add any child Components.
In other words, you cannot create a Component Blueprint with child Components. Pretty shocking!!

What I would like is to have a Component Editor with Viewport so that you can work like Actor Editor.

This seems quite logical but it is not supported from UE.
