Allocate Stock to all products in BOM

Good afternoon,

I would like to be able to allocate all items in a BOM when I allocate the main product in a sales order.

For example I have a Master Product, which is made up of 5 parts. When I generate a sales order with 1Qty Master product and click allocate stock, I would like all the 5 parts to show as 1Qty allocated under "products and services". Once I generate a despatch note and the order is complete, all 5 parts will be deducted from stock.

Is this currently possible in Sage 50? Is there a workaround anyone can suggest?
