Expand XML fields - ShipByDate
Please upgrade/update the XML schema to be closer in alignment with your API models. Currently, for example, I'm unable to pass "shipByDate" via XML for custom stores. I don't have API access to another company's shipstation because they have sensitive data. They would prefer to use a "Custom Store" via the XML feed, but we're unable to send sufficient data points like you can in the API.
Ideally, the data points should match between API and XML feed.
