I2S time slots and DMA buffers

I want to use the DMA controller with the I2S interface (now the SAI on the 120MHz Kinetis K60).  When I go to setup a DMA channel with PE, it allows me to define the number of time slots but only one buffer to transmit or receive from.

 

It would seem that if the DMA channel could split up the time slots, it would require X number of buffers for X number of time slots but I don’t see any capability to set up this buffer structure.  Can PE arrange to DMA time slots to separate buffers?
