@foone This is why every time I start making KiCAD stuff, I dust off the little DSL I made ten years ago to plop out custom symbols and footprints. No I would not like to put a 40-pin symbol on my schematic when I'm using 5 lines of this poor microcontroller, save that for the gerbers I want a tailored symbol for this design!
Alas, it's very old crumbly python, and rewriting it is currently behind "reimplement Unicode" on the todo list, so...
