Shipping / Billing countries

Would it be possible to restrict different countries from the shipping / billing drop-downs?

I.E. Ship address limited to countries A,B, andC.
Bill address limited to countries A,B,C and D (or vv.).

One way would be to add a couple of fields to the zones table -
published_billing
published_shipping

One for the wishlist?

I don't see that as coming soon as a feature in HikaShop honestly. That's a lot of work and not practical to implement. First, because custom zone fields can be used for other things than the addresses. Second, because you can have the same address for both billing and shipping and that's the case by default...so it complexifies everything for not much.

It would be way easier to just edit a view of the checkout and add a check on the addresses country to tell the user that country X is not possible for billing or shipping and remove the next button until the user corrects the country.

Thanks.

The changes described here shipping-and-billing-addresses might provide another way of handling this.
