Hey guys does anyone know how i can make a custom instance portal that leads to an area of my choosing so i can make something like totc work?

Well the instance portals already present is triggered by Area Triggers.
You step into an area and it teleports you.

So I guess you could just make an NPC or a Game Object teleport players instead.
