Calling RPCs on actors with no owning connection

Is there any easier workaround for calling RPCs from actors that are not owned by a net connection?

Currently, I have a component that is attached to my player controller and some actors in the game world. Whenever I need to send an RPC I pass my player controller component reference to the actor in the game world, it does reroute the RPC to be called from the player controller.

But this way forces me to implement everything in the base component class in case if I needed to inherit.
