If Michael's suggestion is not appropriate for any reason ...

If you have a backup of the AR Data immediately prior to the retrieval, While no one is in the system, it would be possible to "save the existing AR data", do a temporary AR only restore and open AR just to consolidate and GL just to retrieve, put back the "saved existing AR data", delete the unconsolidated GL batch that is no longer needed.
