How to set default region so next sls initialization adds region to .yml file

To save an editing step with the serverless.yml file to manually add a region (or save from having to specify --region in the deploy command), is there a way to set initial values (such as region to us-west-2, for example) so that when creating a new project with the ‘serverless’ command those default values get added to the serverless.yml file that gets created?

Seems like $HOME/.serverlessrc would be the appropriate place to have it with something like:

"defaults": {
    "provider": {
        "region": "us-west-2"
