Multiplayer - Creating Instanced Quests for Individual Players

Hello community, I need some advice.

I’ve developed a quest system where a player interacts with an NPC, selects a quest, and activates it. The quest might involve collecting specific items or defeating certain mobs. Currently, the quest operates in an open world with other players.

My question is: Is there a way in UDK5 to create a player-only instance on the server where the player is teleported to a specific map to complete the quest?

This is a common system in MMORPGs where a player activates a quest and enters their own instance. They can also bring a friend from their group if they wish.
