Changing the problem a bit, I'd recommend moving away from the CCSDS
encoder/decoder blocks and using the FEC API blocks, instead. See:

http://gnuradio.org/doc/doxygen/page_fec.html

The CC Encoder and CC Decoder are basically the CCSDS codes (you might have
to swap the two polynomials; I always forget off the top of my head which
is called which code here).
