2nd MIDI port input for Kontakt (ie MIDI ports 17-32)

Hi,
 
Has anyone tried setting up a second MIDI port in to Kontakt? It looks like 4 are possible, but somthing needs to be set up in SONAR - for Kontakt to see more than just one MIDI port (channels 1-16).
 
I don't really have a need for more than 16 MIDI channels at the moment - but I'm just getting my head around Kontakt, and wondering if or how this is possible to set up in SONAR.
 
I'm pretty sure I've got my head around the Kontakt outputs (I saw the thread here too late) and have set up some track templates in SONAR for some Kontakt setups. Now I'm wondering if it's possible to set up a monster multi with 32 MIDI channels.
 
Thanks for any info...
