Changing one client to a new map without disconnecting it

Is there a way (In LAN) to let one client load a map server don’t have, but not disconnecting that client to the server? Or the other way around, let server load a map that client don’t have, and make the client stay at the map server was without disnecting the client?
I noticed that APlayerController::ClientTravel can

  • If called from a server, will instruct the particular client to travel to the new map (but stay connected to the current server)
    How can I manage to do that?
