quoteDuring with octave transposition

[Paul Scott]

2.13.61

I have been doing all of this manually until recently that I saw how 
useful \cueDuring and QuoteDuring were.  Thank you Lily developers!!

The example in NR 1.6.3 Quoting other voices is too complicated for me.  
I thought I had seen a command go by on the list that I could use to 
quote a flute passage an octave lower in the clarinet.

After giving the right \transposition for the clarinet \addQuote and 
\quoteDuring work fine for me to quote the flute part as is sounds.  I 
just want the clarinet to double the flute passage an octave lower.

Any help would be very much appreciated,
