Mapping mixed-mode s-parameter table to the actual parameters

I'm working with a 12-port s-parameter model, which represents 3 differential channels. I've read a bit on the conversion to mixed-mode s-parameters for differential/common-mode analysis, and I understand how a 4-port network would get mapped to a Sdd/Scd/Sdc/Scc matrix (ref: the very bottom of this part of the LineSim docs… ), but it's not obvious to me how this would be done for a 12-port file. Is there a convention for this, and what is it?
