I'm unsure of what model of scanner we have at our local UPS branch (Obetz, OH), but when a bag is missing a label, how do you link the packages inside to a bag to scan them? I know I was trained how to do it, but I've been in the primary for awhile and have forgotten how to do it completely. It's kind of embarrassing to ask one of the other guys...hoping someone on here could help...thanks in advance.
