Include header in Send Transactional email (templates)

[armaseg]

By now, is it possible to add a mail header when we send a Transactional email (without templates) so it's really useful to add tags and other custom fields.

$mailin->send_email($to,$subject,$from,$html,$text,$cc,$bcc,$replyto,$attachment,$headers)

I think it would be nice to add this option when we send Transactional email (templates)
