Rotating slanted wall

[Horchloeffel]

I'm playing on PS5, but maybe I can get help here to. I'm flipping the "in harmony with nature" house in the forest and it has these slanted walls around the windows. I accidentally deleted one and now I can't get it rotated so that it fits. It's always like a ramp from the ground up. Even when I copy one of the others. Is it even possible?

I did the exact same when I played that one lol but no I don't think it's possible in story mode..we really need the transform tool in story..
