Just found a video which exploits a hack to draw footprints on Copper.
The Idea is to first draw some graphics on the silk screen in the Footprint Editor.
Then Right Mouse Button and change the line segment to a copper layer.
The “very dangerous” part is that KiCad can not do DRC error checking and such on these line segments, so you have to check manually.
The Footprints are also text files and you probably can change the layer name of some graphics right there with an editor. (Haven’t tried).
