Customize Guide/Gather follower emails

We would like the ability to customize follower emails for sections/topics/articles/posts in both guide and gather. 

The ‘trigger’ functionality for sending ticketing emails has been very useful, and allowed us enough customization to make the system work for our company. However, being unable to edit the content of follower emails has made it difficult for end users to tell what the email is pertaining to at first glance (and many won't open an email if the subject line doesn't make sense). 

Being able to customize content by setting branding in the subject line or introductory sentence would greatly improve our users' forum experiences. 

Is this feature in the roadmap? Are there workarounds?

I see many other users have posted regarding this shortcoming but have not seen any official news about it.
