focus-effect: circles grouped in different direction

Hey everyone,

does anybody know how to created an effect, so that the main part runs in different direction? For example I have eight movig head spots on stage. Four as a left wing, four as a right wing. Now I want them to run circles. I want them to climb from outside and sink again in the middle of the stage.

So I want them to move like this:

 

At the moment I create an circle effect, copy it and reverse it and use the first effect on the left wing, the second on the right wing, but I search an easy way to do it fast.

Thx
