Deploying Lambda to multiple regions does not work

Hello,

My .ask/config has the following content:

{
  "deploy_settings": {
    "default": {
      "skill_id": "amzn1.ask.skill.[skill-id]",
      "was_cloned": false,
      "merge": {
        "manifest": {
          "apis": {
            "custom": {
              "endpoint": {
                "uri": "arn:aws:lambda:eu-west-1:[function-name]"
              },
              "regions": {
                "EU": {
                  "endpoint": {
                    "uri": "arn:aws:lambda:eu-west-1:[function-name]"
                  }
                },
                "NA": {
                  "endpoint": {
                    "uri": "arn:aws:lambda:us-east-1:[function-name]"
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

$ ask deploy --target lambda
Lambda deployment finished.
Lambda function(s) updated:
  [Lambda ARN] arn:aws:lambda:eu-west-1:[function-name]

When I try to deploy the functions, only the default one will be deployed. Maybe I'm not understanding correctly, but shouldn't it deploy for all regions?

How do I deploy all of them at once?

Thank you!
