Confirmation for sub-operation

Hi Expert,

As we know that confirmation has to be maintaned for each work order confirmation.

Current condition, we also have to maintained confirmation for each work order sub-operation.

Is there any possibility that only operation level of work order that need to be confirmed? instead of sub-operation level? in assumption that work order created with both operation and sub-operation

illiustration:

Operation 0010 Greasing

Sub operation 0010/0011 cleanning

Sub operation 0010/0012 inspection

Confirmation conducted for operation 0010 Greasing only, instead of all operation and sub operations

Thanks

Pls Help
