Leave Key in a specific position

Hello all,

I am in Switzerland, using a Kaba 20 double cylinder lock. It has the function whereby if there is a key in the inside (as needed in Nuki) then the door cannot be opened from the outside.

It also has a function where if you leave the inside key at a particular angle/rotation, you can push it out from the outside and unlock the door as per normal.

Is it possible to finely calibrate the Nuki, so that when it locks, it always leaves the key at this rotation, so that if for whatever reason everything fails, i can still get into my door?



I have exactly the same request/question.
Have anybody found something about this ?
