The only way to do this is adding the component to the base class of all those actors. Just create a blueprint class with the component and derive your other actors from it.
Each time you add a component to an individual actor in the scene you are basically creating a new blueprint class. I would advice you not to do that at all.
You should, everytime you can, create a blueprint class, edit it and adding all the components you need and then placing it in the scene. Always edit the class and never the instances (unless you need something specific to that instance).
