aftertouch midi learn ? (gor glissando in guitar instru)

Hi,
I'd like to use aftertouch to replace soft pedal for the glissando effect in the guitar, but it doesn't get recognized in midi learn.
Nor it have a midi cc number. In Reaper iut's named "channel pressure".
Is there a way to make Pianoteq recognize after touch ?

edit : I just figured-out the keyswitches still can be used even "easy" mode.
