De-interleaving SPORT data via DMA on 21469

I'm curious to know if there is an efficient way to use DMA to de-interleave i2s or TDM data that is received on a SPORT.  The only method I can devise involves using single count TCBs and changing the destination address in the ISR.  I would rather set my count to my block size and not interrupt the core until the data is all received in de-interleaved.  Is this possible?
