Is it possible to pause a contoured motion?

I'm using the NI-73xx palette to construct a contoured pattern. Everything works fine, but it won't be practical until I can get it to pause and resume exactly where it left off. I tried using the velocity override VI but couldn't get it to work. I think it's because contoured motion calculates the velocity for you, so you can't change it even if you tried to set it. Any ideas? Thanks!
