Answer:Currently the concurrent reactions work only with global orientation. This is a limitation and has already been put into the development list. Personally, I wouldn't recommend taking the components of global concurrent reactions. I say this because the vehicle position causing max Fx and concurrent Fy may not be the same as the vehicle position causing Max Fx (local).
Right now, the only way to ensure proper concurrent reactions based on local axes would be by use of moving load tracer. All required vehicle positions would have to be converted into static load using this.
