New Zoho Books - Issue with Custom Email Templates

We've been testing the new Zoho Books interface and it is a huge improvement over the old one. One very important thing I noticed though, is that our custom (HTML) email templates with logos and badges have been reverted to plain text. Are we going to lose all those customizations by moving to the new Books? Are those even possible with the new Books?
