Default confirmation type in confirmation screen

Dear expert,

I want to set 'final confirmation' in confirmation screen(COR6N), i entrance OPK1 to set 'final confirmation' is default.

But I want to some order type set 'auto final confirmation'.  How I can do that?

I try to set in 'OPK4' then go to 'COR6N' is not to be change.

I think system can set 'confirmation profile' and assign to order type, please tell me how to set?

thank you,
