title: Dynamically add entries to alexa custom slot type s
body: <p>I have developed an Alexa skill and in one of the intents made it a to have a custom slot type. The custom slot type is nothing but a very specific, specialized list of strings.</p>
  
  <p>My question is how to dynamically add entries to the list, is there an API on Amazon side that I could call from my code to dynamically add new entries and retain the model?</p>
