Configuring a multi company environment I found that child companies would need to see the parent company stock (it's required by the parent company) while keeping their own stock.

I've seen that if I put the parent company warehouse with an empty Company, the actual stock of products is reflected in every product list of the child companies, however, the idea would be to have the data separated.

Is there any workaround to make this possible? I tried to read the documentation deeply but can't find the way, I think it would be possible creating a new account for the parent company which only can access to the stock, but it would be better if the user don't have the need of logging out and in just to check for the stock.
