"Finished goods" and "parts and materials" in same warehouse?

I have a physical warehouse space that houses both finished goods for sale and has parts for manufacturing. I want to have the finished goods in the “finished goods” account and the parts and materials in the “parts and materials” account, but have both in the same warehouse in ERPNext. To do this, do I need to create two separate sub-warehouses under the main warehouse (the actual, physical one) - one for finished goods and one for parts and materials, while routing them to their respective accounts?

You could also use the racks/bins functionality.
