Sage100 2013 PU8 Packaging requirements breaks negative shipments

So for the life of our time with SageERP we have been using negative sales orders to create RMAs to the customer.  The negative SO would be "shipped" which would then generate the credit to the customer and bring inventory back into stock.

As of PU8 the package quantity needs to match the shipping quantity and will not accept a negative amount in the package.  This basically renders our current RMA system useless.

Any suggestions on getting around the package requirement or a different way to do an RMA without the module?
