Survey > Actions > Email Task sent to multiple recipients

I set up an email task under action so when a survey response is submitted, a notification email is sent out. This email is currently going out to multiple people, I added them with the comma separation in the "To:" field. The system sends out the email to the recipients individually, so the recipients cannot start a conversation as they don't see each others on the email. Is there any way to overcome this, or perhaps set it up different so the survey response is distributed to a group of people and they all see each other? I do not with to set up a ticket, as this is just a notification and doesn't require any action. Thanks for the help. Anna
