Maintenance of Sales / Fields Staff in the Customer Master

Dear All

We are having Sales / Field Staff hierarchy as follows

ZSM ( Zone Code / Description / Zonal Sales Manager's Name / From Date / To Date )

RSM ( Region Code / Description / Regional Sales Manager's Name / From Date / To Date )

ASM ( Area Code / Description / Area Sales Manager's Name / From Date / To Date )

ASO/ASE ( Head Quarter Code / Description / Area Sales Officer or Executive's Name / From Date / To Date )

which are maintained in 4 Z tables. These codes are maintained in the customer master against each customer using an enhancement.

Can I achieve th same using standard configuration? if yes, please provide me with configuration details.

Apart from this I want to add one more level as Sales employee below ASO/ASE.

Please guide me with configuration steps.

Thanks in advance.

Regards
