CR XI - Shipping Labels Report - Qty Calculation/Display Options per Label?

Hello Experts,
One of our largest customers has put a product labeling standard in place that we must follow in order to continue doing business with them. Using CR XI I have created a template for labels (4"x5.375", 4 per sheet). To meet the customers specs we need to label each carton and each package as to contents and quantities. Per shipment, contents (part number) will remain the same, but quantities will change based on label placement. I understand how to do everything, i.e. parameters, barcodes (downloaded font), etc. But I don't how, or if it is even possible, to change the quantities printed on each label. I haven't found anyway to differentiate between the labels in the template to be able to direct different Qty values to the individual labels.

Example Scenario: We want to ship 430 items (same part number), they will all fit in one carton, but we will have separate packages in the carton with 50 in each and another package with a remainder of 30. So, we will need 10 labels total, 1 Qty 430 (outside carton), 8 Qty 50 (each full package), and 1 Qty 30 (remainder package). I understand how to create the parameters and the formulas to do the math, but is there a way to apply the different quantities to each label, thus creating all 10 labels with a single run of the report?  Will I need to alter my template to create a subreport for each label, if so how do I change the layout on the fly?  

Any help is greatly appreciated.  TIA!
