DB180

my A7 got the memory seat in driver side however, since my family members hv different preferences on their own seat adjustment, they hv to adjust the seat every time they sit on passenger side.
i had a check on A7 part catalog and found there is a memory seat button available for the passenger seat (my car is a right steering one, which i can use the memory seat button originally for left steering A7).
im just thinking about if i install the memory seat button for the passenger seat, can i just simply "code" the car to enable the memory seat for passenger side? or there are some more parts i hv to replace before making it come true?
my passenger seat is electronic adjustable so that's why i think installing the button with coding is possible. any ideas?
