XF 1.4 How to undelete a user's posts?


Well-known member
Is there a quick way to undelete all of a user's posts/content? A staff member on a forum I run got a bit power-hungry and got pissy at a fellow staff member and banned & deleted all of his posts. I can still view them as they were only a soft delete but how can I undelete them all by bulk? Is this possible? :)
