Add EU, NATO to the drop-down list in country & add sport selection option

Hi Team,

Can you please add EU, NATO to the drop-down list in country field?

Or can you please advise how I can do it from my own?

As I can see you have flags in your plugin (sports-leagues/vendor/world-flags-sprite/stylesheets/flags32.css?ver=0.11.0), but the names are missed in drop-down list.

Also will be useful to have an additional option for selection a sport type for the teams.
For example:
Barcelona has Basketball, Football and other teams. Will be good to have an option to select sport for relevant team.  

Thanks in advance
