title: Training improvements on new actions builder
body: <p>I am building an new action. I have multiple intents, and I added ~20 training phases for each of them. However the matching seems to be pretty terrible</p>
  <p>I have webhooks configured for the scenes. I look at the raw query and the handler that was matched. I have the exact phrase in the training phrases, but a different intent gets matched.</p>
  <p>It seems like old Dialogflow interface had a way to improve training (<a href="https://cloud.google.com/dialogflow/es/docs/training#tool" rel="nofollow noreferrer">https://cloud.google.com/dialogflow/es/docs/training#tool</a>) allowing you to match actual queries with the right intents. Is there an equivalent tool for the new actions builder?</p>
