It might be worth breaking this out into a separate YML file given we are starting to amass quite a few keys.

You can adjust the I18n load path like so:

```rb
Rails.application.config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
```

Then you could structure the configs like so:

```
- config
-- locals
--- en.yml 
--- cy.yml
--- car_campaigns
---- en.yml 
---- cy.yml
```
