Collaboration on email templates

It would be nice if we could collaborate on Email templates within Gainsight, the way we can with say, a google doc. 

We almost always draft emails in a Google doc, so that we can collaborate with multiple editors and approvers. If we could even have a hyperlink to an email template to share with Gainsight users, that would be a good first step, but I'd love to see some way of inviting non-Gainsight users to at least view and comment on email templates as well.

Part of the reason we have so many issues with Copying/Pasting into email templates in GS is because we're always copying in a "finished" email.
