Instanced Zone question

[Randymarsh9]

I want to try something where there will be an instanced zone that people with a certain qglobal can get into and otherwise would go to the regular zone. Do you think I could do something where an NPC creates an instance when it spawns and then everyone who asks to be sent to the instanced zone will all go to the exact same zone? I know how I could set it up so everyone goes to their own individual instance, but I want them to actually be in the exact same one like they would in a regular zone.
