Discount UPS Quoted rates on 2nd, 3rd items but not the 1st or Oversized items.

By the way. One thought I had was to add a 3rd rule that somehow added the amount that had been discounted back in. But I can't figure out how to apply that rule to trigger only on the Oversized item that has been discounted and not anything else. And of course, the 1st oversized item, which was not discounted, should not have anything added back in.

Basically it would be like this:

Rule #2 first discounts all shipping per item after the 1st highest item.

Rule #3 finds all "Oversized" items, (ignores the 1st one since it's always going to be the highest, non-discounted item), and then adds the amount(s) of the discounted shipping back in for the 2nd "Oversized" item(s).
