As the subject mentions, the "Set Carrier/Service/Package" automaton action when making an automation rule only lets you select from your preferred carriers. We as a company are required to use around 9 different shipping accounts and I would love to be able to automate all that rather than have to set it on each individual order. Hopefully ShipStation devs see this and make a change. Doesn't seem like that intricate of a change to just allow us to use all our carriers.
