Selection of STO document Item in VL10B for Delivery creation

Hi, Experts,

Currently we are using VL10B transaction code for delivery creation agsinst STO document. But in VL10B, STO document is only selection paramter. But now as per our business requirement, They want STO document as wel as STO item  in VL10B selection. So can we take STO item as a selection parameter in VL10B through user role setting , If yes, Then give me exact setting for that.

Thanks a lot in advance.

Regards,
