Show available stocks for a specific warehouse in sales order

Hi All,

running v9.0 pl11.

In the sales documents, on the lines, the users have a column showing the total stock availability per item, across all warehouses. For product A1, stock for warehouse WA shows an available quantity of 10 and stock for warehouse WB shows an available quantity of 7. If I go to the sales order document, the available quantity shows 17.

How can I get a column that shows the stocks for each warehouse alongside the total stock availability on my sales order?
