Automatic Response for Acknowledged Message

When a message is acknowledged, we want the driver to know we got his message by receiving a an automated message back when we hit acknowledge. For example, if a driver sends "it is a slow pour" and we hit acknowledge, he might not think we actually read it. But if we hit acknowledge and he gets a message back, like "10/4 thank you" he knows we received it. An automated message when we hit acknowledge so we do not have to type it out or hit the reply button, would be nice.
