WebFig - Skin Edit - Change/Add Comment Column in Static DNS section?

In the example screenshot, I’d like to have the comments listed where it says “Desired Comment Location”, rather than on a separate line.

Various docs say to just "download the file from /skins, edit it… "

Except that there is nothing there until you edit something using WebFig Design Skin - and then that is only a JSON file.
