Yes, but that's nowhere near as simple nor effective as a turn dial.

This is just another example of the brain-dead designers and coders running around ruining the world.

It sounds extreme to say, but I suspect quite a few of them have blood and misery on their hands, because some poorly designed control cascaded in effect and caused a catastrophe elsewhere. It's easier to imagine with medical equipment than microwaves, but its still putting someone's desire to write fancy control algorithms over a simpler more effective design.

Start out by punching any jackass insisting everything be digital, you will go a long way to solving the problem of bad designers.
