Second Floor L Stairs?

I havent really seen an answer to this, Is there a way to make L-Stairs on a second floor going to the third? I followed some tutorials on youtube for making them on the ground level to 2nd. But when I try the same method on a second to third, it doesnt work. I even tried to make the 1x1 tile on a detached ground level and then selecting the option to move the square, but upon placing the two shorter ones they just disappear entirely. I'm trying to make a stairway to an Attic so having that smaller footprint of an L-stair would be extremely helpful with the sloped roof.
