Yes. That's what the gate function is for, to link your maps together.
All you have to do is to write a valid mapname for a map you have installed in the game, either in your exports or in your terrain folder as an unexported map.
The thing is, when you assign a map to a gate, you must write the correct mapname, and not the display name.
For instance, I might make a map displayed as "Derp Valley", but the actual map name in the map maker might be "derpvalley" and that is what you'd need to give the gate since it checks for the map name.
Other than the name, it's just the coordinates of where you are going to end up in that map.
