How do I specify a CodeDeploy application and deployment group name in SAM template?

I'm using a SAM template for B/G deployment. The problem is a CodeDeploy resource is automatically created. Is it possible to specify a name for application and deployment group?

If you enable gradual deployments through your AWS SAM template, a CodeDeploy resource is automatically created for you. You can view the CodeDeploy resource directly through the AWS Management Console.
