Can I find just the apps which I have purchased in the App Store? I know I can go to the Purchased tab in the App Store on my iPad to see all the apps that I have downloaded, but I have been unable to find a way to see just the apps that I have bought.

Is there a way to sort the apps in the iOS App Store so that one can easily view all the paid apps that have been downloaded?
I don't know of any way to do this using the App Store.  I look through my email receipts for this information.
