Change default diameter hole waterline

Hello everyone. I need to change the default diameter in the creation of the water circuit in EMX, in the options there is the entry WATERLINE_DESIGNER_DEFAULT_COMPONENT set like this:
mm | meusburger | E2080_8_10 && mm | meusburger | E2000_13_14 && mm | meusburger | E2130_11_8_2_4 && mm | meusburger | HOLE_8, where I assume that HOLE_8 is an instance present in the HOLE.dat file, I should bring the default value to 8.5, in the file HOLE.dat I inserted a line with the name of the instance HOLE_8_5 but changing the options mm | meusburger | E2080_8_10 && mm | meusburger | E2000_13_14 && mm | meusburger | E2130_11_8_2_4 && mm | meusburger | HOLE_8_5 when I launch the creation of the circuit it always remains Ø8, something wrong?
