How to change accounting class "Inventory Valuation" for Manual Cost Adjustment ?

Summary:

When the PO price is updated after receipt, the system posts an acquisition cost adjustment that debits Inventory Valuation, but this does not correctly update the average cost. To correct the average cost, we perform a manual user cost adjustment, which also impacts Inventory Valuation. As a result, Inventory Valuation is affected twice—once by the system adjustment and again by the manual correction—leading to an overstated item valuation.

We would like to change the entry going into Inventory valuation to a different accounting class like EXPENSE or In transit Inventory . Is it possible to acheive this using SLA JERS & JLR ? I don't see option to change accounting class (Journal Line Rule).
