Visibility to see if a Return Package has been uploaded to a Target Language Content Block in the Translation Task

A vendor has requested to have visibility to see if a Return Package from Trados Studio has been uploaded to a Target Language Content Block before completing the Translation Task.  Some XML/DITA Projects coming in from Tridion can have many Translation Tasks (500+), having visibility to which Target Languages have had a Return Package uploaded to would help with managing large projects.
