The Operator can, it's all about how you address the lights. If you have a 5 channel light, just address the second light 6 instead of 17. It does make programming pretty tedious, though. You could also adress the second light 9 and use the page buttons to distinguish between fixtures. I suppose that wouldn't be as bad.
AND if you want the lights to do the same thing, just address them the same. You could invert the pan on one if the fixture has that feature.
I'd go for the separate page thing, but again, it would be harder to program than just using the fixture buttons.
