Hello, I'm wondering if anyone has any suggestions on how best to setup this scenario in Odoo.

Bullet points:

- The business has 4 physical warehouses.

- The products are mostly all pre-order based / ordered in advanced.

- The website has both pre-order and available now (remaining stock) products.

- Business does not know which warehouse a product will be in until it's arrived at port and shipped to that warehouse.

What is the best way to allow a customer to purchase products from all 4 warehouses and allow the warehouse staff to easily pick pack and deliver from those 4 warehouses?

I've attempted to setup a Virtual Warehouse with the 4 warehouses under it so that all 4 can be sold from, but this doesn't help in regards to picking, packing and delivery, as it creates those all under the virtual warehouse and not each individual warehouse.

Off the top of my head, the only thing I can think of is some action that splits a pick between 4 warehouses depending what is set in the initial pick in the virtual warehouse. But I was wondering if I'm missing some easier way of doing this.
