Replace Country records in location Field with Italian City records

referring this post: https://premium.wpmudev.org/forums/topic/add-more-specification-in-jobexpert-location

as a temporary solution for my needs to have more fields for Jobs&Experts location maybe can I edit the location country list to replace it with italian city list? Is a solution for you? Let me know if is possible and which part of plugin I need to edit.
Thank you in advance
