Have parents receive trial confirmation email when added manually by admin

When I register a student manually in a class using Registration Manager, they receive an email confirmation with the details of their registration. But when I register a student manually for a TRIAL, there is no history of the system ever sending a confirmation to their parents. I'm also not sure that the system sends the Personal Assistant reminder email for trials, unless the parent schedules the trial themselves. Could you please make the confirmation emails go out regardless of who schedules the trial?
