title: Is there a way to do nested variables in VSTS Release Management
body: <p>I have a few variables created in Variable Groups with the following names:</p>
  
  <pre><code>CodeNetworkShare.Dev
  CodeNetworkShare.Test
  CodeNetworkShare.Prod
  </code></pre>
  
  <p>I imported this variable group in my Release Definition. Then I tried the following ways to use this in Release definition </p>
  
  <ol>
  <li><p>I created a local variable in the Release Definition as follows: </p>
  
  <p>Name = CodeNetworkShare1
  Value = $(CodeNetworkShare.$(Release.EnvironmentName))</p></li>
  <li><p>I tried to use it directly in the task using the following expression:</p>
  
  <p>$(CodeNetworkShare.$(Release.EnvironmentName))</p></li>
  </ol>
  
  <p>Neither of the above approaches worked. Is there any other way I can get this to work? Does VSTS Release Definitions nested variables? If it's not supported at the moment are there plans to support this in the future?</p>
