In the documentation (docs.textadventures.co.uk/quest/showing_a_map.html), it says you can make a single room with multiple locations by setting the Border Type to "Path North" or "Path South" to connect rooms. It then says to "Set the exit length to zero in both directions."

There is no option to set exit length to any number, and simply setting the borders to Path North or South doesn't link the rooms.

Is there a way to do this in the GUI, and if not, what code do I need to insert to set the exit length?

I thought exit lengths had something to do with the map that's optional to show up.

You can connect multiple exits to a room, but it's confusing...

You click on the exit itself in the map tree, then go to its Map tab:

If you've seen the map Quest displays it works in a grid consisting of lots of 1x1 length squares, exits also take up a single square but display a line instead of a bordered box so if you have length of 0 then this exit will be displayed flush against the room it's leaving and you'll have 2 boxes next to each other.

You can also set rooms to take up multiple squares in width or height, so in order for exits to compensate you need to ensure the exits are also the same length if they are running parallel to that room.

Ah, I missed that... Thanks! It works perfectly now!
