Customer Credit Memo Report

I would like to pull a report that shows all open / unapplied credit memos for our customers. I was able to run a transaction list by customer report and filter by transaction type > credit memo but that seems to be showing me ALL credit memos rather than just the ones that have yet to be applied to an invoice or are pending. I would like to be able to see just the credit memos that are outstanding / owed to our customers. I am using Quickbooks Enterprise Solutions: Contractor 21.0 (Desktop Version).
