How can we load the freight cost to the item at inventory.

Hello

We are creating PO and at the time of creation of the PO we don't have the freight so when we do GRN we got the invoice along with the freight on the same invoice, So when we create invoice matching with the PO i got freight/Misc check box through that we add the the freight but that cost can't be landed to the item cost to the inventory, But we are not using LCM module.
