Transfer Order Consumption at Item level

As per current design the transfer order demands only consume forecasts with customer/customer site set to the organization customer/customer site value in the supply network mode. Can we achive TO consumption at Item level as well (similar to sales order)

For Example,

Total Forecast = 20 , consist 2 customers (Cust A - 15 , Cust B - 5)

If we receive TO of 20 Qty for Cust A , As per current design system will consume only 15 (Forecast at Cust A) . Our requirement is that TO should consume entire forecast of 20 .
