Apparently the packing slip is the Sales Shipment -report (printed from posted sales shipment)? And hopefully I understood your idea correctly.
From from posted sales invoice, you can seek "Item Shipment Lines" on the Lines -fastab: Line --> Item Shipment Lines. From there you find the right posted sales shipment.
Or if the sales invoice is posted from sales order, you will find "Order No." from posted sales order. This can be used as a filtering criteria in the posted sales shipments list. Thus the relevant shipments will be found.
