How to include Freight Cost in Cost Distribution

Hello

We have created a PO for $100. And created invoice for $150

1st line matched to PO $100 and 2nd line for freight $50 (Manually added on Invoice)

We accounted the invoice and ran the cost and receipt accounting process but Freight cost is not showing up cost distributions.

Is there a way to include this Freight charge which was manually added on invoice will come in Cost distributions

Thanks
