It would be wonderful if Trados would forward the QA results the translator worked on to the return package QA action. Maybe with a boolean like QaRun = True if you ran the QA within the last x minutes or hours before creating the return package. If it's set to yes, then skip the QA process during return package and attach the QA results.
It's just very annoying to see exactly the same errors you worked on 2 minutes ago pop up again in the QA results of the return package action. That's just redundant and doubles the work.
