Redundant Chargers Feature Needed

Can you add a filter to my route plan that will allow me to only be routed to charging locations with more than one provider near by. This would allow me to arrive at a charging provider and have a backup charger provider if the first one had an issue and couldn't charge my car. Nothing worse than getting to a charger with 5% left and it will not charge and the next closest charger is 50 miles away. Thanks, AL (Bartlett, IL)
