I dont exactly know what you are looking for but you dont have configuration when your point was saved in joints.
Configuration indicates how the robot access the point. Using Cartesian the few ways to be a the same point under difference pose, under joint config there is only one way
I hace a cell in robcad,so i can know in each point of the path the value of the robot axes and the cartesian coordinates. I dont have fanuc controller for robcad, so my goal is to make a macro in excel where i put the values of the axes in each point and i get a path in .ls with the correct configuration. The problem is that i dont know how to calculate the U/D T/B
