Items Numbering on Line Items tab

Hello experts,

My client has a requirement in which SAP CLM's Master Agreements should have the same numbering behaviour for items used in SAP ECC which is start number 10 and increment of 10.

I'd like to confirm if this is not possible on SAP CLM 7.0 as I didn't find anywhere to change this setting.

Thanks in advance.

Kind Regards,

Robert
