I'm relative new on Serverless, I'm building now a lambda function and I need to deploy that same function on different stages and also different regions, for example for `development` stage I need to deploy to `us-est-1` region and for `production` stage I need to deploy to a different region, how can I do that using my branches, for example when I do a merge to `develop` use `us-est-1` region and then when code is merge to `master` branch use `us-est-2` region?

Thanks in advance
