I love this firmware!!!

Could you please add the extruder motor step setting on menu?  I am using a third-party extruder set,  gear ratio is 1:3, It need to set the extruder moto step to 3x for ultimaker 2,They provide a custom firmware to do it.  but it is in chinese and I don't know the version, so please add this function, thank you very much.
