SPAD.next A32nx Engine mode switch

Hi all
Hoping that someone out there has an answer to this for me please.
I’m looking at mapping the TCA throttle engine mode button to SPAD.next but for the life of me I am unable to find the setting.
I can select the knob and its position but when I try to map it to a function there is no option for the ign, norm or Crank mode.
Has anyone done this yet as the msfs update seems to have broken something and it now just flicks back and forth.

Hi! I attach a print screen of my config. It has been working without problems for over a year (I have not downloaded and tried sim update 9 yet though). Hope it may help you!

Hi
Thank you so much for this. Worked a treat. Spent a while on this yesterday trying to make it work.
Finally moving all my cntrols away from the sim its self and using spad, much easier and nicer to work with.
Thanks again.
