title: Getting current CF stack value with Serverless
body: <p>Is it possible to read the current value for a particular parameter, (say <code>functions.function.memorySize</code>) and then alter it (say I add a few gigs to it) dynamically in <a href="https://www.serverless.com/" rel="nofollow noreferrer"><code>serverless.yml</code></a>?</p>
