Removing countries from Rest of the World option

Hi I have a single flat shipping rate for international (rest of the world). There are 200+ countries in this option. I would like to remove one country from this option. Is this possible to do? I would hate to have to go though and manually add countries to ROTW option just to exclude one...

Replying to this comment in the hopes it gets a response; I also need this because I'm excluding from the UK for VAT purposes, and a few smaller countries that have big shipping disruptions

You can set shipping settings for individual countries by adding them by name. The ‘rest of the world’ setting applies to every country that hasn’t been set up with individual settings (as above).
 

It isn’t possible to add ‘no shipping’ exceptions to the ‘rest of the world’ category. If you want to ship to limited countries, you just add each one (even if it is 100 of them) and avoid using the rotw category.
