title: Can we use a regex in the synonyms for LUIS list model?
body: <p>I want to use a list model. Can I use the regex in the synonym list? For example:</p>
  
  <pre><code>{'canonicalForm': 'cat',
   'list': ['kitty',
    'c*']}
  </code></pre>
  
  <p>I want my model to return "cat" for "kitty", "cccccc", "chiuoiu", and any other string starting with "c".</p>
