Forza Motorsport 7 and Forza Motorsport 23 has the ability to flip and snap rotate/move an object quite easily. A feature that is lacking in Horizon titles that would make livery and vinyl creating much more efficient and effective. It would be nice to see this feature become a feature someday on Horizon 5 or a future Horizon title. Being able to build off of this concept such as choosing your own snap distances and rotations would be lovely as well.
You have to flip the completed decal once its already on the car. Kind of a pain, but its a work around for matching car sides.
