[itsm] Ticket Phone - Form modification

Hi, please let me know if it's possible modify the position of the fields in the Ticket Phone form.Can it be done changing the configuration of the system or the dtl file must be modified? In the file \Kernel\Config\defaults.pm is mentioned that in the path \Kernel\Config\Files there is a file called Ticket.pm, but in this path there is no file with that name. I suppose in that file could be done the requiered modifications of the ticket fields. Thanks and regards. Daniel. _________________________________________________________________
