Reimport same product

Hello,

I would like option to re import same products so i can change Shipping country or variations for example.

Now i choose USA Shipping, but one day i might want to add China, but it’s not possible now without deleting product.

Is it difficult to make?

Great plugin in general, only after import we cannot change such things.
Maybe let us override same product?

just an idea

thank you
