Can an elimination journal be reversed?

We have a separate entity for consolidations and we run our eliminations and consolidations in that entity. Our exchange rates may have been incorrect for the dates the rates were pulled, so the entry was incorrect. We have since corrected the exchange rates. Is there a way to reverse the elimination journal that was created and posted? We don’t have any manual journals set up in the consolidation company. Also, we need it to reverse using the same exchange rates it used originally.

Thanks.
