Only One Cycle Layers Per Group Allowed?

I'm trying to have my character do a cycle layers, one direction, then after some time do it the other direction.  Pause doesn't seem to be working.  My character, a news anchor, is holding papers in his hand.  The cycle layers is used to animate him bringing the papers up close to read them.  After a time, he needs to return his hand to its normal position or run the cycle in reverse.

I have his normal arm with papers as one group, and the cycle layers as another, so I could swap set them.  It works fine going one direction.  I figured I'd try to add a second cycle behavior to the group, to cycle in the reverse direction, but I don't see how to trigger it.  Adding a group with two cycle behaviors to a swap set doesn't allow you to select which cycle behavior to trigger, so they both trigger.

I know the pause option is way easier, but it doesn't seem to work here.  Does the trigger for a paused cycle behavior have to be an actual trigger?  My cycle starts when triggered by a swap set.  But when I hit the swap set trigger a second time to have it continue after pause, nothing happens.
