Sorry for the late response.
I called them for some asking something, and the the call center agent noticed that I had paid for the seat selection, so she said that untill the departure of the flight I could 'transfer' the booking of the seat in another reservation.
I hung up, look my reservations, I call again, speak to a different lady, and I selected a seat in an another flight.
