Q: AWS Beanstalk default domain wildcard cname prefix

I would like to have wildcard domains for an auto-scaling application running on AWS Beanstalk.

I cannot use a custom domain with Route53 or alternatives, so I am forced to use the default generated domain format, eg: "environment-name.elasticbeanstalk.com".

I would like to have something like this "*.environment-name.elasticbeanstalk.com" configured at the load balancer level for my setup.

Does anyone know if there is a way to specify a wildcard domain prefix for the beanstalk applications running with the default domain?
