Don't route older Tesla's to CCS type stations

I have a 2018 Model 3 which I haven’t yet done the CCS upgrade. When I planned a route from Greenville, SC to San Francisco, and even though I selected NACS, it suggests a lot of IONNA chargers which only work if you have the CCS gen 4 conversion done (see How to enable CCS1 adapter/NACS support on older Model 3/Ys) even if you use the NACS connector. So you might need a separate filter for that. For now I need it to be pure Tesla Superchargers.
