Access-Control-Allow-Origin: <HostDomain>

How can I include the above header in the mashup that snippet that is generated. I've already included the domain as a Trusted Origin and have the appropriate content policy mapped to the Application but still facing issues with Cross Domain errors on few scenarios. So would like to add our parent site's domain as part of the Mashup header.
