Currently, you have to manually update the RAG status. The idea is that the system automatically updates the RAG based on the due date. Also make the task status in the GANTT view more visible if in amber or red status. The task shows a red border if overdue, but it's not as visible. The whole block should be red, amber or green based on due date. This could be system-driven or customised. Eg. 2 days from due date, turns amber.
