Modify Bitbucket email notification content by Project

Bitbucket email notifications, resulting from reviewer comments, contain snippets of code along with the comment.  We would like to to configure our BitBucket notification scheme to only show the comment without the code snippets or eliminate the comment/code from the notification all together.

In the perfect world we'd like to be able to do this for some but not all projects. Is this possible? 

If not, where are the email templates stored and can we modify them in place?

Thank you.
