Octagonal roof adjustment

I was soooo thrilled at the addition of octagonal roofs, as I use that room shape a lot. Then I found out that you can only make 'square' octagonal roofs, and they more often then not totally don't align with the room I make, therefore rendering them useless more often then not. I would like to know if others also feel that octagonal roofs (and maybe the round ones too) should be re-adjustable in two directions just like the square ones?
