Is difficult because this information is contained on recording db coll, not on transcription db coll. Option is to start keeping this info on transcription docs, or just grab via a second call to server for each transcription , to look up its recording db entry.

for new pieces, needs to be updated in acceNewPieceInfo function, in both teh .clone, as well as the "else". BUT, in order to test the cloning, will need to do the aggregation first.
