Erase atmegas (fuse setting)

Rup

Erasing atmega328P sets fuses not to manufacturer default. Where is fuse setting (used for erase function) stored? I must set fuses manually everytime after erasing. Can I edit fuse settings used for erase function (simply set them according to manufacturer default)? Thanks

If I clear m328p using erase command, I must then manualy set fusses to get IC "as from factory" in default state. Then if I erase m8a then I must manualy set its fuses again. Even if I want to clear more ICs of same kind I must "erase" and then "program fuses manualy" for all ICs cleared, twice time, twice clicks. Not so good in 21st century. This makes erace command quite useless. I´m surprised there is nothing like an *.ini file for "erase" command setting.

May be I should prepare and save project with all FFs and fuses properly set according to datasheet (prepare "erased IC" project), programming such project will clear IC better way than current clear command...
