I Can't Find the Numbering Scheme Setting

I Want to change the name unity automatically Gives a copy of a object Like:

v Current Numbering Scheme v

ObjectA_1 < The Original Object Name

ObjectA_1 (1) < The Copy of The Original Object Name

and i want to change it so unity automatically changes it to that

v Numbering Scheme I Want v

ObjectA_1 < The Original Object Name

ObjectA_2 < The Copy of The Original Object Name

I found multiple posts about this but everyone of them sayed

Go To “Edit->Project Settings…->Editor->Numbering Scheme” But it is not there for me.
