Adding the barcode field to the On/Offsite reports

Is there any way with 7.5 to change what fields are available for the onsite and offsite picking lists? Our tape handling teams are changing and the new one only wants the complete label in the report, IE, adding the L4/L5/L6, etc to the 6 character media ID we normally get. You can see this in the media sections of the GUI, so NBU knows it. It seems to make sense that this would be helpful with tape handling reports. Is there an XML file or script that can be modified to do this. Thanks.
