BOM item included in Sales order but not updating quantity for sub-items of BOM

Steps Followed

  1. As We tried to Create a New-BOM Item which includes to sub-items with quantity values as 1 and 2.
  2. Then i tried to include this BOM Item in New Sales Order, but then Quantities values of Sub-items of BOM Item is not updated in Sales Order.

It should update Quantity values for Sub-Items and secondly can we select warehouse while adding sub-Items to BOM Item.

Can anyone assist on this Question if it is present in ERPNext or Not.
