2 Part Label for UPS

When we used UPS WorldShip, we printed on a roll of labels that had a 4 x 6 1/4 in label followed by a 4 x 2 label. The larger label went on the package. The smaller label contained some shipment summary info and we would peel it off and stick it onto our paperwork. I would like to have the option to use this label format in ShipStation. 99% of the labels we print are for UPS.
