Jay,

switches. Probable cost more but the above issues go away and you could
store multiple configurations.

Actually I don't think it would.
You'd need only one small micro, and a few bits.
You could have a 'pot' for setting the value and a button for select/recall.
Lower parts count = less cost :-)
