Wrong Job Posted on AP Invoice

I have searched high and low and I can't believe that no one else has done this and there isn't a solution for it!

I have several AP Invoices that have the wrong job# posted to them and they have been paid.  What is the easiest way to fix these so the vendor costs goes to the right job since I see that I can't do anything in the job costs screen after it's been paid.

Thank you!
