We have different ship via’s setup like you pointed out. In our company, it makes it easier on the order entry folks, and the shipping folks - so everyone is on the same page with how the order needs to be processed.
I don’t think you need to set it up that way, as you can check most of the boxes off on a per-order basis in the Header Manifest Info tab.
