Displaying MISC charges in report

Hi everybody,

We have a Shipping performance report that displays Order -> Line -> Release, Invoiced/Not Invoiced/Total for a range of ShipDtl.ShipDate 

I've been asked to include the Misc. charges from these orders, but since the Misc charges are at the line level and there doesn't seem to be a one-to-one relationship, how can this be accomplished? 

Thank you,
