Customizing Webinar Emails

Looks like there's been a big change in the way registration and panelist emails are created/edited over the past couple of months.  The email templates are now different and even more generically poor.  So do I now need to deal with all that HTML code to change the reg and panelist emails for one of my webinars?  Seems like a whole lot of work, so perhaps I am missing something and there is an easier way.
