Usage

The function enables to compare the results of application of a ticket filter(s) with the results of application of some other filter(s) on the same package contents. Apply the first filter and save the package contents to a file. Then use the Undo function to restore the original package contents and apply the other filter. Now you can compare the current package contents with previously saved file using the Match Tickets in a File filter. This way you can create multiple branches of package modifications.

The function is also handy when incorrectly specified filter settings remove all tickets from the package.
