Tracking story submissions to multiple publications using Outliner?

Currently, I track story submissions to a dozen publications using a spreadsheet. I wonder if anyone is using the Scrivener Outline to do this?

Question: How do you keep track of your short stories under review and prevent submitting the same story to the same publication or the same story to multiple publications?

Thanks!

I track my pitches to magazine editors using Scrivener and I use labels to categorise each submission (yellow for waiting for response, green for commissioned, red for rejected, etc). Might that help?

I use the Submission Grinder website. It keeps track of most markets and includes aggregate stats on response times from the other users.
