Automatically lock doors at 15 km/h?

Hello, I recently bought a Picasso. In the previous car (golf) here (brasil model) the doors are automatically locked at about 15 km/h. I miss this little “extra” in safety at the Citroen. I know from this forum that some VW drivers simply “programmed” this function in the workshop, which is probably not active in the German Gulf. Is this possible with the Picasso too? Other question, the FB of the lock is def (mechanical, kei How much does it cost in D or does someone have a different suggestion (accessory… maybe even folding lock conversion)? Greetings Christian
