title: Is it possible to change the PowerAautomate Customer Connector Request Header during runtime?
body: <p>I have a Custom Power Connector which uses a custom http header in its request. The value of this request need to be different from request to request. Is there a standard way to achieve this?</p>
  <p>I tried adding a 'set http header' policy to the connector but it only allows to set one predefined value to the header. Is there a way to add a variable to it?</p>
