Batch Shipping sort by Ebay Listing Number

Hello there,
I'm thinking about using ShipRush for my Ebay's USPS shipping after having success with ShipRush for FedEX. I just have one question:

Can I group all the orders by Ebay Listing number; for example: 12345, for batch printing. Then assign custom SKU to be printed on the shipping label: abcd.?

Basically, I want all the orders from listing 12345 printed with SKU abcd on the label with one click. Can I with ShipRush?
