title: Alexa Skill - Update Intent programmatically
body: <p>I'm trying to create an Alexa skill which has a fairly wide-open possible number of phrases it could use. Too many to write by hand.</p>
  
  <p>I can probably generate the list programmatically, but it changes frequently, so I'd want it updated frequently.</p>
  
  <p>Is there an Amazon API I can call to update the possible values for a custom slot type, without having to manually log in and copy and paste it all the time?</p>
