There is no feature like this, but I would suggest creating tasks in Confluence to remind users, and then you can even set up something like Task Reminder for Confluence to email them when they don't have completed tasks.
Note that you won't be able to automate this using Confluence tasks, so you'll want to make sure to add the task manually with the desired date and user mention in order for it to work with the add-on.
I hope this helps!
