Thank you for joining us here in the Community, @seswende.
The option to record the credit with one step isn't currently available in QuickBooks Online. I can certainly submit feedback for you to our product developers for it to be a possible option with future updates. For information on future updates coming to QuickBooks Online, you can take a peek at The QuickBooks Blog.
If you run into any bumps in the road and need assistance with anything else, I'm only a reply away.
