Good morning, @DavidRDavis ...
Unfortunately, this is not a current function of Canvas. However, there is long-standing Feature Idea that you can participate in that seems to be similar to what you are requesting. You can find it at: Automatic due date reminder notifications - Instructure Community (canvaslms.com). If you feel this Feature Idea aligns with something you'd like to see implemented in Canvas, you can give it a "star" rating, and you can also leave a comment on it as to why you'd like to see it implemented. Give real-world examples...as those are great for Instructure to learn more about our experiences.
Sorry I don't have better news for you, but I hope this helps to answer your question.
