Applying Credit Memo to an a/p invoice

When you create a credit memo, you can associate it to the a/p invoice with the Correct UNmatched invoice (for non PO); however I don't see a way to actually APPLY the credit or debit memo to the a/p invoice to reduce the amount actually owed. The only way I see it is to pull the Credit / Debit Memo into the PPR or Create Payment and apply them together. Most ERPs you'll see an Original Invoice amount and a balance for that invoice….is this possible in Fusion?
