Mass edit history restore
 

One of my members got their accounts compromised and had hundreds of their posts edited to gibberish. The old posts are still in the edit history, but it'd take a really long time for me to edit them all manually. Is there anyway to restore them all at once to their previous version, or restore them to an edit made prior to a certain date, eg. January 15th 2013. The member had made several edits of the posts themselves over the years so I want to keep those edits in tact and not restore to the "original" post, but rather the last version before the attack. All of the posts were edited over the course of a few hours if that helps.
