Custom Information in Registration Mail

I have two questions for the registration mail.

Can I add a additional information to the registration field, dependent on the course?
Best would be, when I have an additional field in the course edit form, something like "text that is added in the registration confirmation mail". so it would be possible to add course dependet information.

You can edit the event, look at Advanced Settings tab. There are settings on that tab to allow you to enter message for that event only

Enter message you want there and it will be used for that event (instead of the one in Events Booking -> Emails & Messages)
