pick list print issue?

Hello Friends,

I have a printing issue with my client,

For specific customers they ship very large kits(BOM's) and require ship labels to print for each component listed on the picklist , in addition to the regular ship label for the header material YX.

These components are item category YF (purposely omitted for delivery note).

They do not want this to print of every customer, Please advice how we can add a logic to print shipping labels for components only for specific customers.

thanks;

Mike
