slave configuration ignoring the eeprom

In older version it was possible to write custom Sync Manager configuration.
After the update ec_configlist.h was deleted.
I dont know where I could place my coustom configuration.

 {/*Man=*/0x0000AED0,/*ID=*/0x00000100,/*Name=*/"open:I/O Slaves"  ,/*dtype=*/7,/*Ibits=*/1144,/*Obits=*/680,/*SM2a*/0x1800,/*SM2f*/0x00010064,/*SM3a*/0x1c00,/*SM3f*/0x00010020,/*FM0ac*/1,/*FM1ac*/1},

any Ideas?
