Email Preview as Specific Recipient in Message Templates Similar to Marketing Emails

It’s difficult to test Message Templates unless you execute them on a test account and wait to receive them in your inbox. There’s no clear view of the email as a whole from the edit screen if it gets long.

From the Action menu on a Message Template, I’d like to be able to Preview the Email as specific recipient same as how I can do when working with Marketing Emails. Please and thank you!
