When turning multiple pieces of Wall into Gates, you can select normally non-gateable pieces of the Wall (The short "walls" as well as the square "caps") and they may also be turned into a Wall.
Additionally, if you do this and select unbuilt pieces of wall, they will be turned into a 1 HP gate that cannot be repaired or built.
Attached is a screenshot with a "short gate" that was previously one of the square cap walls.
