Rear thrust angle and toe adjustment possible?

So I was going in for an alignment today, and in looking through the FSM for the alignment specs i see all three angles are adjustable in front, but nothing for the rear. I usually like a little more camber and less toe up front.

There are no settings for the rear, as it turns out there are no adjustments.

Is there any way to increase toe and camber in the rear, or at least straighten the thrust angle?

There is a small thrust angle present and one wheel with negative and one with positive toe.

 

Has anyone used these before? How do they work?
