Has anyone ever use use intercompany transactions with inventory item? Is it easy to use?

you are using cross-subsidiary fulfillment? It works well. Waaay better than what we used to do....SO creates PO in other sub > SO > Drop Ship Fulfillment > Vendor Bill

In this scenario, can items from subsidiaries not listed as "default" be displayed on the web store? Or would you need to add an item to multiple subs in order to get it to show up?
