how do i change spawn point for second floor

[meeeeme]

its tiring making a hallway with a arrow at the end to use to go to the location i want the player to only to remember that the next floor has the same borders and inow you cant go more forward because you took up all space and you have to make some maze like design to combat it why cant i make it that spawn points for the second floor are on the center of the border not exactly where the previous one ended
