Triggering Event For Specific Client

I’m new to UE4 and trying to figure out how to create zone portal triggers for specific clients. The end result of what I’m building is a multiplayer cluster of dedicated servers each hosting a specific map. Each map has 1 or more “portals” that trigger transfer between servers for that client only.

What is the best way to set this up? Right now for testing I have a trigger box set up at the necessary location. In my Level Blueprint I am calling OnActor BeginOverlap (TriggerBox) ----> ExecuteConsoleCommand(open “IP ADDRESS”)

It works however now that I think about it, won’t this level change happen for EVERY player regardless of who overlaps the trigger at any point? How would I go about specifying events to occur for ONLY the person who actually triggered the event.

Thank you.
