Hello, Can Credit memo (only amount and not quantity ) against a PO/Invoice, update average cost

Summary:

We have a scenario where a some credit is to be applied to supplier for invoice charge , can this credit memo be matched to an Item to update the average cost using Landed cost management?

We have a scenario where PO is raised, Item received and Invoice matched to PO. We know this process will update the item average cost. However, subsequently due to some price correction, we need to manually create debit/credit memo (-ve amount) to supplier. We know we can match Invoice line type, Item or freight, or misc. charges thru landed cost management and update the average cost, but wanted to check if we can do for CM/DM having -ve value as well?
