We use a third party API to process our shipments to Amazon FBA. Carriers for LTL are assigned by Amazon with no input from us, the shipper. There is a specific Carrier that rarely services our area, yet are routinely assigned pickups. This causes significant delays to our inbound shipping schedule and inventory stock counts. Does anyone know if I can I delete this particular Carrier from our LTL options list? Can I choose between multiple LTL Carriers and see their costs - similar to how we choose shipping for FBM orders? We would be willing to pay more for other Carriers if it means they shipments get picked up when they're scheduled.
