In the WooGeolocation plugin for WooCommerce we have a feature called “Custom regions” where you could group under a common name some places and use that in the rest of the plugin to save time instead of typing all the names once and over again in the different places of your website.
By default, we provide some hardcoded regions for countries which are the continents. So in case you want to geotarget South America on any place of the plugin you just need to use the region called “south-america” instead of typing all countries every time.
You can also create regions for States, Cities, and zip codes. Along with these regions we have something called map regions.
