Wildcard subdomains

Hi, is it possible to implement wildcard custom domains for api gateway? In other words, *.users.example.com. Amazon made an announcement about a year ago about this feature. I’m trying to create custom endpoints for each user.

https://docs.aws.amazon.com/apigateway/latest/developerguide/how-to-custom-domains.html#wildcard-custom-domain-names

I’m using the serverless-domain-manager, but this requires a redefinition of each subdomain though it is serviced by the the same lambda function.
