Hi again,
I understand your explanation, thank you very much. But, the main problem is that.
UPS and DHL zones contain different countries. For example:
USA: Zone 1 for DHL, Zone 2 for UPS
Georgia: Zone 3 for DHL, Zone 5 for UPS
So how can I combine UPS and DHL in the same zone?
All shipping companies have different country list in the different zones.
