Freight

I know when running autoinvoice you can not have more than one frieght line as it will combine them.

Is there any way around this ? and if so how do you do this?

Our invoice has freight at the delivery level not the lines level - so when we ship we add the frieght at the delivery tab. We defined a fuel surcharge

under those frieght codes but it doesnt seem to come out on the invoice as a separate line.
