It is possible that turn-on-with-motion, turn-off-manually is built into
some motion-detector-switch. What happens when your switch comes on with
motion and you turn it off. I presume you saw your switch stays on for
an adjustable time. Check the manual for the 3-way version of the switch
you have what happens when it turns on with motion and then the 3-way
circuit is turned on and off.
It could be done with a relay, but that is a lot of complication.
As John said, you might want to use a 3-way version of what you have.
