We would love to see the ability to reprocess only single records or a selected group of records from exceptions. For instance, in our exceptions bucket, there is a mix of legitimate exceptions, and RE token expired exceptions. We'd love to just be able to reprocess the token expired ones and leave the legitimate exceptions in the bucket.
We recently made an update to resolve the 'RE Token Expired' issue - so you shouldn't be seeing those exceptions any more! Please let us know if that's not the case.
