[BY DESIGN] "Set as Front Door" Problems

The problem seems to happen if you place a deck or room above and overhanging an outside door. It's as if the coding states that if a build item occupies a space above and in front of a door, that door is now set as an inside door. If you have a deck in front of your door, it's fine as long as you don't give it a ceiling. Once you do, your door also becomes an inside door.

The only way to correct this is to give outside doors a different code, which means you would either have to separate the doors into different groups so people know, or change the code on all doors so that inside doors could become front doors. The only other alternative that I could possibly see is to just give the first door or the last door placed in the house, front door status. This is probably why this problem hasn't been addressed before as I really can't see an elegant solution.

Yet more: Perhaps somebody else can give this some thought, and see if they can figure out how to address this problem?
