IC Lot Quantity For Costing (not to be mistaken for "quantity shippable") - how to adjust/edit?

Hello All,

Does anyone know how (without going through SQL) to modify the columns "Quantity for Costing" under the lot tracking module? IC Lot Reconciliation and IC Adjustments merely affect the "quantity shippable". We're trying to modify the "quantity for costing" as well as the "cost for costing".

Current environment is: Sage 300 v 2014, PU 1

Any help would be appreciated! Thanks!
