Streamline the process when including 1 additional person in the reservation.

It would be very useful to speed up the process when it comes to include 1 more person in the reservation, at the time of check-in. That is, when we have made a reservation for 1 person and finally 2 come, as only the option to scan 1 person, we have to get into the reservation put 2 people and then exit the app to be updated and the option to scan the 2nd person appears, and sometimes it takes time to update.
