title: How can I create a list of a combination of attributes in API.AI (Dialogflow)
body: <p>I have a requirement where I want to accept a list of 2 attributes from API.AI, for example, the user can say any of the following:</p>
  
  <p>add 2 oranges and 3 bananas 2 my cart</p>
  
  <p>add 2 oranges 3 bananas and 5 apples to my cart</p>
  
  <p>So it should send a list of the combination of count and fruit-name to my application. Any suggestions?</p>
