Make Sesami able to add additional and complementary information to the Customer Profile - already existing. Having phone/e-mail/name/last name as required fields at the time of booking (for example: Instant Booking), if the Client's profile has already been created without some of these fields, the 'additional' information will not be added to the Customer Profile. (Or in case the customer has changed the phone? email?) [Sesami App doesn't change the customer's profile - keeps the existing and already provided information.]
