Currently, you can only filter by MAPPED service or Marketplace value. This is problematic if a customer later wants to upgrade shipping, and someone on our team changes their shipping service to FedEx Express, for example.
There's no way to filter our orders to show these express orders along side any that were originally mapped to express.
There should be a way to filter by service that is currently chosen, not just mapped or requested service, but the service that's selected within shipstation.
