title: Select different region on serverless based on branch
body: <p>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 <code>development</code> stage I need to deploy to <code>us-est-1</code> region and for <code>production</code> 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 <code>develop</code> use <code>us-est-1</code> region and then when code is merge to <code>master</code> branch use <code>us-est-2</code> region?</p>
  <p>Thanks in advance</p>
