I try to create a new carrier which has 200 ToCountries. They are the same as another existing Carrier. I didn’t find a way to copy or duplicate+bulk changing the Carrier. So I tried to CSV export Carrier selection, with three columns:
Carrier/ID From Country/ID To Country/ID
and réimport them with the Carrier/ID corrected. This doesn’t work (“Object error in importing the file”).
I tried using Carrier product name and country 3 letters codes too.
How is this possible for a user to create a many-countries Carrier selection without doing a one-by-one line creation?
