Door View Cam - European market

Hello, I have completed the kit for my apartment with the last accessory in subject. I succeeded in solving the problem of the "short" bracket for the Italian security door but there remains the problem of the flat cable which is short. It would be enough if it were 2 cm longer. Is there any possibility of finding it or getting it, even aftermarket, with this length? Are you planning to make a product intended for the European market with armored doors over 55mm? Thank you.
