Shiny new basement hatches but can only place one?

I was trying out the new hatches and apart from being entrances they're also good looking decorations would it be possible to allow for more than one to be placed at a time?

 

Sure, right after we can have more than one basement!

 

if you have more than one hatch leading to the basement, when you leave the basement, which one should it put you at? there'd be extra tech needed to store the location you entered from, rather than just "the basement hatch on lot x", and even more tech if you wanted to go in one way and out another (which would admittedly make for awesome maze building)

 

To limit the extra tech you should always be placed at the hatch you used to enter with, some of that already exists as you can recall/teleport out of a town and enter again by via a teleport scroll you land where you left.
