Choosing POD supplier based on user location

I am using Printify POD for a series of printed coffee mugs. There are multiple suppliers worldwide who can fulfill the same product. Can I designate that, for example, a US-based user will get the product from a US vendor – and not, say, from a European POD vendor? The issue is shipping costs – if a customer is in the US, it’s obviously cheapest to have the order printed and shipped in the US. Likewise, a customer in Europe should get their order printed and shipped in Europe.

What are you trying to achieve:
To differentiate where a customer is based, and use a POD vendor in that customer’s geography. The actual product ordered is the same, the only issue is where it’s getting printed and shipped from.
