How can I route orders to ignore a dummy warehouse location in Shopify?

[dbw-775]

We have a real warehouse setup with actual stock.

And a 'dummy' warehouse which effectively acts to show available stock we know is in our suppliers warehouse.  We don't dropship orders, but when an order is placed for stock we don't have, it can be ordered into us the next day.

So we're basically using this dummy supplier warehouse location in order to show certain products as in stock, knowing that with our shipping options we can ship on time even after buying it in to our main warehouse.

The problem when it comes to order routing is that Shopify correctly allocates the stock from new orders to this dummy warehouse.

I'd like Shopify to still query the that warehouse so as to treat it as available stock.

And yet at the same time at the point of order routing, I want that dummy location to be ignored completely and instead just routed to our actual warehouse location.

Is this possible?

Maybe there's another way to solve this I've not thought of too?

I can't think of a way to do it with order routing settings because it assigns the location expecting that that location will fulfill the items.

The manual way I guess would be filtering orders by location and checking once a day orders for that dummy location to see if they should be changed to your warehouse location. You could use Order Automator app to automate that, for example you could create a rule so that if a product is assigned the dummy warehouse and has the tag / sku / title / stock / etc then change location to your warehouse location.
