We have no plans to implement multistate values within notifications at this time. However, I did want to share a method by which this can be accomplished. If you configure a PI Vision display with a multistate symbol, you can include a screenshot of this display within the PI Notifications email. Please see more information here: https://docs.osisoft.com/bundle/pi-server/page/add-a-screenshot-in-notification-email-delivery-format.html
