Nope. At least, I've never heard of that. I would not bother, but if it really bugs you, you might just buy some foilcals off eBay, cut off the right-hand area around the knobs, turn the two pieces upside down and switch sides with them, use some removable adhesive to cover up the original foilcals, and reorient the knobs on the shafts. Done properly it might look OK.
Maybe. :saywhat:
