"No Code" method to add to parameter to Email Message Header?

Hi.  

I am following up on a thread I posted earlier which seems to have withered -- I am looking for an alternate path.    (Link to original thread is below)

Is there a "No Code" way to add to the email headers that Creatio generates? 

I know there is a way to code the email, but we have so many processes that send out emails, I will have to hire a developer to do this.   (Code is included below for reference, you can see there the header I need to add to the outbound emails)

If we could add "X-Auto-Response-Suppress: All" to the header, we would eliminate most if not all "out of office" responses we get back.

Thanks
Rob

var message = new Terrasoft.Mail.Sender.EmailMessage
{
	// Sender email address.
	From = "Sender@email.com",
	// Recipient email addresses.
	To = new List<string>{ "first@recepient.co", "second@recepient.co" },
	// Copy optional
	Cc = new List<string>{ "first@recepient.co", "second@recepient.co" },
	// Hidden copy optional
	Bcc = new List<string>{ "first@recepient.co", "second@recepient.co" },
	Subject = "Message subject",
	// Email body.
	Body = "Body",
	// Priority, Terrasoft.Mail.Sender.EmailPriority enumeration values.
	Priority = Terrasoft.Mail.Sender.EmailPriority.Normal,
	// Headers you want to add to your email
	HeaderProperties = new List<Mail.Sender.EmailMessageHeader>
	{
		new Mail.Sender.EmailMessageHeader
		{
			Name = "X-Auto-Response-Suppress",
			Value = "All"
		}
	}
};
