Shared Reminder Notifications

My wife and I share a grocery list on a shared reminders list. We are having an issue that whenever one of us adds to the list the other person doesn't receive any sort of notification. The correct settings in the notification center are selected alerts, badges, etc. but nothing happens. I would love for there to be a notification when something was added to the list just like when an event is added to a shared calendar... is that possible?

Thank you for any and all help!
