Mautic.org plugin for Auto Assignment of lead ownership

Hi, I need a custom plugin for Mautic. The plugin has to assign automatically the ownership of the lead based on the country of origin of the user. So when Mautic receives the lead information, there is going to be a field with the list of countries. Plugin will detect which country is and assign automatically the ownership to a specific user of the system. So the plugin should have place where I can create groups of countries and choose which user is going to be the owner of that lead. Thanks
