Creating multiple stages for one api

By default whenever you deploy a stage it creates a whole new api endpoint.

So example would be:

https://cojn6cbcd9.execute-api.us-east-1.amazonaws.com/test/handler
https://uojn6cbce7.execute-api.us-east-1.amazonaws.com/dev/handler
https://abcn6cbce7.execute-api.us-east-1.amazonaws.com/prod/handler

This takes up space on aws and we just hit a 120 limit due to this problem. Me and my team were wondering if there is a way to make one api and for the stages to be put under that one api.

We can do this manually but cannot figure out how to do it from serverless if it is at all possibly.
