Send Update via email address in an automation

I have a board that I want to restrict users to, so they will submit new items through a form. After the form submission they need to follow-up later with a link to a presentation they need to complete. I would like them to do that with the Update via email option where they can send the link to the presentation and it will be captured in the board via an update. I don’t want to have to manually send the Update via email address to the submitter. I’d like to use an email automation upon item creation to send them an email and include the Update via email address in the body of the message. I don’t see that field available - wanted to see if anyone has done this or is this in the pipeline for a new feature?
