Aggregate multi services under one http server

I do not know if this is a feature request or a question, but what I want is the ability to use one server for multiple services. If our application is built as monorepo, and each service has its own serverless file, I would like to be able to run one *server* for all services.

What I need to do now is setting a different port for each.

Is there anyway to achieve this functionality?

Thanks.
