Expected behavior

I'm writing a plugin to bounce or block outbound messages based on certain conditions. I am able to receive the message content in the hook_queue and block the message using the following snippet.
next(DENY, 'blocking the message');

What I want to do more is customize the bounce message that gets sent to the sender on the DENY return code or add a customized banner to the original message so that it shows up as part of the bounce message.

Is there support in haraka to achieve any of the above two options?
