How can I setup AWS API Gateway mappings using serverless.ts?

Let’s say base path is: [dev.mycompany.com](http://dev.mycompany.com)  
How can I set a mapping suffix for the API Gateway?

- [https://dev.mycompany.com/my-new-mapping](https://dev.mycompany.com/my-new-mapping)  
(Not a subdomain but a suffix).
