Hi Klonsemann,
Nice work with your script!
Regarding your first question about RC not being flexible enough for your workflow? Can you elaborate please as I am currently creating similar objects with windows and awnings above other windows vertically.
As a side note, I found that Its easier to make additional windows within 1 container as you have shown in your screenshot by plugging 1 railclone into another railclone as the default segment (or top/bottom), which allows you to easily stack different types of windows vertically and horizontally, unless im mistaking what your trying to achieve.
