Support for Trailer Hook limits on hill gradient

Owners of VW Group MEB Plattform Vehicles (ID./Skoda E/Cupra/Ford E) aswell as Tesla (Model 3), Hyundai Ioniq 5/Kia EV6 and other models with a trailer hook have their CoC hook loads specified for lower than 8% gradient. This restriction seems to come from peak power versus permanent power and cooling limits.

As you use height data for calculation, a feature to exclude gradients higher than 8% in route planning would be great.
