Shopify Marketplace Connect

We've used Codisto for awhile and it could be better. The old eBay app used to allow us to choose locations by item. They didn't have a location option until we addressed it with them and was a serious teeth-pulling episode. Eventually they came up with the means to pick ONE location which we figured out a way to manage (despite the fact that some items come from one location and some from another). Now with Walmart Marketplace ending and this app being official (?), the Walmart portion does not have a place to choose locations where the product is coming from. So we sold items out of a location that doesn't have shipping facilities. Why can 2 of them have location option and not Walmart? If this cannot be updated immediately, we'll have to find another app (which I would rather have have to do).
