Accounting for 800v cars at 400v chargers

I can find any documentation about it, but it seems pretty clear to me that the routing algorithm does not consider the massive time penalty of charging an 800v car at a 400v charger. For a given model, the maximum 400v power is a known figure. In my first long trip with my Lucid Air + NACS converter, I've noticed it's was way too keen to send me to a Tesla Supercharger, even if there's a 800v option across the street. I realize there's an option for preferred providers that I could use to deprioritize Tesla, but that's not a good option. Newest generation Tesla charger actually do support 800v, and maybe some 800v chargers are so unreliable or low power that I'd rather take the 400v penalty. I need an app to figure this out for me!
