How to Edit Poly Aftertouch?

Hi all,
 
I'm trying to figure out how to best edit MIDI poly AT data in Sonar.  It appears we can edit it in the Event List but not in the Piano Roll, so it's sufficient in a pinch but, clearly, it's not ideal:
 

 
So, what are our options?  I've scoured the docs and forums and found nothing.  I figure there must be some CAL scripts or other workarounds - maybe a script that separates poly AT onto note-specific CCs for temporary graphical editing in the Piano Roll and then another one to put 'em back?  I looked at the default CAL scripts but didn't see anything obvious.
 
Any assistance is greatly appreciated.

I can try to write AZ Lua preset to do the conversion, the difference with CAL is that it can work "real time" (you can hear the modification without bouncing/processing first).
 
But I do not have any good idea to what should I convert it for editing. Key After-touch requires 2 value, the key and the value. So either it will "consume" the whole normal key range (not practical since continuous) or the whole CC range (can clash with "normal" CC, creates one "CC lane" for every note with KA).

Hi Promidi
Could you please post your channel to poly aftertouch cal routine?

Here you go.  Remember, save often.  I have had some CAL crash sonar inexplicably for some unknown reason. Usual disclaimers apply. I am not responsible if this crashes your sonar, sets your cat on fire and blows up your power supply, etc..

Copy and paste the text between "begin code" and "end code" and save the file as a *.cal and you're good to go.

Note: I did test this in Sonar Platinum and it worked fine.  The best way to see the conversion is to have an event viewer window open while running the CAL to ensure correct conversion.

Can CAL copy and paste data between tracks?  If so, then I'd go with the latter approach - copy just the notes and Poly AT data to a new track for temporary editing.  This way, you can put the AT data for each note in its own CC lane without fear of conflict.  When done editing, another CAL script would be required to convert the data back and merge the tracks.
 
Just a thought.
 
Thanks for looking at it.
