Fred, can't understand the source for this confusion. I want any
switch to be able to turn ON/OFF the lights as before. It's just
that I need to be able to 'set' them all up at least once in
their lifetime so that late at night it's easier to figure out
which switch turned on the light.

(1) You CAN'T figure this out by looking at only one of the switches. It simply is not possible.
(2) If the light can be turned on by any of the switches, it can also be turned off by any of the
switches -- which means it does not matter which one turned it on. You can turn it off from ANY
of them, not just the one that turned it on.
