This is something our large customers are crying out for and with the development of the Evri Shopify app to make the installation seamless I think this needs looking into.
Each Parcel Shop has it's own ID so my understanding is that this needs pulling from Shopify when the order is imported and then transmitting via the courier connector when the label is requested.
Please can this be looked into as it's a significant offering that we currently cannot support.
Also the same for DPD I believe
