title: Is it possible to reference a value in the app.config file somewhere else in the same config file?
body: <p>A recent scenario got me thinking... </p>
  
  <p>I have a key/value pair defining a certain setting in my appSettings section. Later on in the app.config file I have to set a value for an email logger, and I'd like to just use the value from the key/value pair defined in the appSettings section. </p>
  
  <p>How can I do that? Or is it even possible? </p>
