Sorry, we have no method to do that; however, you can enable both "Receive a copy of email sent to buyer" and also "Enable Templated Email", then use our Thank-you Email template variables to format the buyer's Thank-you Email however you wish:

As another alternative, you can use your Seller Admin > Account Preferences > Common Notification URL setting to have all the order data sent via HTTP POST to the URL of a custom script, which could generate an email with the data in whatever format you wish:

If you would like someone to program such a script for you, we can recommend contacting the competent E-junkie-experienced folks listed in our Developer Directory (linked at the very top of all our site pages :^).
