Hello, Seth here, again. I know this may seem odd but that is how the board was produced. They may make another one at some point. Who knows? For now, a button could work. That would take some extra oomph, though. If you want, I can try to help on this matter.
Seth P.S. If you have any electrical set up you want to share on your idea, I can try to alter the schematic or think of another way.
