Manually Send Delivery Reminder Customer Notification

Currently, if a stop is added and routed after the delivery reminder customer notification has been sent out, the customer does not get their timeframe. Can we create a way to manually send that delivery reminder notification on each routing tile? Or if the stop is routed after the delivery reminder was sent out, it will automatically push that notification through to the new stop that was added after the cut off of the set time on the delivery reminder.
