Wall Edge References - Genius Loci

Problem with this one is that if you have an opening cutting through the vertical you don’t really get the full bounding edges of the wall without the openings. I am trying to make this manually with dynamo components, but I am struggling because I can’t seem to match the bounding box faces with walls external faces as per my topic here: Wall Exterior bounding face

I feel like bounding edges of wall that ignores the cutouts would be a useful component in GeniusLoci arsenal.
