To allow for more dynamic CI/CD pipelines (e.g. deploying to multiple regions automatically when a configuration exists), allow for testing whether a particular environment/region combination exists.
Probably return a non-zero status if combination does not exist.
An alternative approach would be to enumerate regions or environments, but this may be more difficult to utilize in a pipeline.
