I am experiencing the same issue and got told to come here as there still isn't a fix. We have two Trading Names under the one Organisation in Xero. I have setup different email templates and logos. However, the massive ugly heading in the email now doesn't match one template as you cannot change this or update for a different Trading Name. Please update this Xero, it's ugly and doesn't work in the real world for businesses who have multiple or different trading names compared to the legal business name.
