We have a dummy element that is a null price to put in the line. You can call it something like /FREIGHT with a gross price of $0. Then in your invoicing elements, you can input whatever you want to credit. AFAIK there just has to be some kind of line in order to create a credit memo, but it can still $0 which means this workaround will work.

Hope this helps,

Thanks, Zoe! 

I guess the issue now is to figure out which category to put in 

Is there a way to not pass the Invoice element when the document is a credit?
