Technically there is nothing preventing kicad from passing this information from the schematic editor to the board editor using the netlist. There has already been a discussion about passing predefined netclass information so this information you presented here is parametric in nature. Of course passing this information is the trivial part. Updating the board editor to handle this parametric information is far more involved.
