I'm wondering whether it is possible to assign customer EAN13 automatically when saving the new customer record.  As this moment you can enter any random number and Odoo will convert to EAN13.  However, I would like to see the ability to assign the last used number and the system will automatically add next one when new customer record is created either via website or staff input.  You just need to give the first 12-digits and Odoo will add the check digit accordingly.
