This would be really helpful. I've been trying various other ways to email a file I created, like uploading it to Google Drive and then attaching it, but there's always a problem with authentication and an auth html page gets emailed instead. I can't put the file onto a public URL because it contains sensitive data (this seems to be the requirement for the Google Mail attachment location).
(I raised this feature request on Slack earlier).
