Enable tagging of multiple prototype apps

Hi, it would great to enable tagging of multiple prototype apps, for its quick and easy deletion. I have now close to 200 prototype and sample apps in my account. I do regular mange/author/copy app in order to backup a working app, since retrieving older versions from within the app often times give a “File not found” error.
As it is now, I have to select an app one by one, and click Delete. Very tedious, specially for many, many apps.
Thank you!
