How to import a refund?

[devfaz]

I am running Firefly III version 5.5.0.beta1

Description
I ordered stuff at amazon and returned it. Of course amazon is so kind to give me my money back (refund).
The problem:

Im using the "remoteName" to map against "opposing account name"

If i try to import this refund with the csv-importer it fails, because amazon is using the same source-account-name/remoteName for payments and refunds. It seems firefly-iii is trying to use the id of the expense-account to to find the suitable revenue-account?

  Line Reset / verification do the same thing #1:

  (2) transactions.0.source_id: Bei der Suche nach der Kennung „15” oder dem Namen „” konnte kein gültiges Quellkonto gefunden werden. (original value: "15")
  (2) transactions.0.source_name: Bei der Suche nach der Kennung „15” oder dem Namen „” konnte kein gültiges Quellkonto gefunden werden. (original value: "(not found)")

So, how can I automate/improve this situation?
