title: How to Set [Activity.From.Id] , [member.Id] or [activity.Recipient.Id] using DirectLine?
body: <p>I'm using MS directline to integrate custom channel with a chatbot based on botframework.</p>
  
  <p>I'm using below functions to generate token &amp; start conversation, but none of them allows to set <code>Context.Activity.From.Id</code>,  <code>MembersAdded.FirstOrDefault().Id</code> , nor <code>Activity.Recipient.Id</code> </p>
  
  <ul>
  <li><code>GenerateTokenForNewConversationAsync()</code></li>
  <li><code>StartConversationAsync()</code></li>
  </ul>
  
  <p>I Know we can control the ID when we send the first user message through directline , but I want to control any of the above IDs before even sending a message from the user. I want to set a specific ID and be able to capture it on the BOT event <code>OnTurnAsync</code> and <code>Activity</code> of type <code>ActivityTypes.ConversationUpdate</code> .. what should I do ?</p>
