Print 2 differnent reports when posting shipment

I would like to print 2 different reports when I post a warehouse shipment. Currently we print a customized report (BOL)

from the shipment (report selections), then we post and print. I tired adding the BOL report to the report selections in Admin\Sales\report selections\sales shipment. But I get an error The BOL report does not a have a data item that uses table 110 sales shipment header. I appreciate any help I can get on this problem.
