pncconf & motor steps per revolution

i have servos with 2500 lines encoders 3000rpm that accept step-dir signals.
I plan to use then with step-dir in closed loop with feedback to linuxcnc.
In option motor steps per revolution pncconf accepts maximum 1000 but my servos need 2500 steps/revolution
Any solution for this ?

try setting the micro steps to 10 and the motor steps to 250

250 X 10 = 2500 steps so that should do it
