Effects Generator Question

I'm trying to set up a search light type scene with 4 scanners in the effects generator section. I'm able to select them all and apply a moving effect. Here is a scenario of how it works, as compare to what I want to do... I'm able to select all the scanners and apply a circular effect. What I want to do is, apply the circular effect to scanners 1&3 and have scanners 2&4 do the opposite circular effect instead of all 4 scanners circling in the same direction. Am I able to do this in the generator instead of having to do it step by step? Thanks!
