As far as I know you've to manually do it. I find it's too difficult to get the tiles to line up, so I don't bother and just set them up next to one another with doors marking the way in and out between them.

it should not be that bad to line them up. you have to check if the grid is correctly alined and then it should snap right in place . also a good idea for lining up is the lift hight all the way down
