Adjusting the subject line in an Email Deployment using the API

Hi,

We have an internal tool that stakeholders use to build their emails in a drag-and-drop WYSIWYG interface.

One of the features of this tool is that it allows users to send themselves a test email (just like you would from within Eloqua itself).

When the API call is fired, the test email is sent successfully. It shows the actual subject line. What I would like to do is, mimic Eloqua's functionality where they put *TEST* before and after the subject line.

Does anybody know how to do this with the API?

Current state: Subject line is This is a test email
