I've got a custom 3-button footpedal I use for work stuff and I'm already having to overload some buttons and now it turns out they've modified the software it interfaces with so now it has 4 possible scan types instead of 2, which is way more than can realistically fit on 3 buttons, especially since I still need buttons for "next project" and "delete last scan".
That's 6 possible commands on 3 pedals. Not realistic or usable even if I could do it
