Charging stations - preferred

Hello,

I am planning to drive from Denmark to Austria and have set up the route to prioritize IONITY and Tesla charging stations. However, the route only includes 0–1 stops at IONITY or Tesla, while the remaining charging points are with operators such as Clever, E.ON, etc.

Could you please provide an explanation or a solution that ensures the route uses only the preferred IONITY and Tesla chargers, rather than various other operators?

Thank you in advance for your assistance.

Best regards, Jan
