How can I create effective return shipping labels?

[Venusmoon]

I need to change the return shipping address when I purchase postage through Shopify.  If I don't purchase postage through Shopify the return address is correct.  How can I change this?

When you use Shopify Shipping to process shipments, the shipping from address and the return address will be the same. You can change this address by editing your locations in Shopify.

However, if you need a different shipping from address or a separate return address, Shopify Shipping does not support this functionality.
