Ensure all Emails generated by RSBlog are customisable

On a Post I get a drop down list to create a pdf, print the post or email a link to the post.

The email that is created does not show on the email page in the backend so that I can customise it but I want to customise it with a standard HTML template i use for all comms.

I understand this email is abnormal in that it uses the standard Joomla MailTo.

Please standardise it to be treated like most emails from RS Components.
