[Suggestion] Adding Steep and Lower Attic Roofs/Windows

[Hypnotic-Sheep]

As far as I am aware, there are only attic roofs/windows for the normal roofs. I wanted to make an A-Frame cabin using this mod, and wanted to add windows in the slanted part, but it seems to not be possible.
(If there is a way to do it, apologies, I did not know)

Attached is a screenshot of how it looks now.
