i realized that there are no transit routes displayed in the SD charts to cross the Airspace of Berne (LSZB) and Geneva (LSBB). these two airports have defined transit routes that they use to grant ctr crossings. A suggestion on how to display such a route would be to show it as a VFR route in SD.
i would appreciate  if you could somehow integrate these transit routes into your charts.

for your reference i have added two screenshots of the respective sections of our ICAO chart.  (my eyes start itching every time i have to look at these cluttered maps, us SD users are so spoiled )

kind regards
