To do this from the TD front end, you will have to have a dropdown user defined object to set the subject, (I assume you mean Function being tested), or some other means to identify a column by in order to filter on it. If you are using requirements and linking them to the test subject that could also be used. Hopefully your various functionalities are associated in their own folders, thereby allowing you to count the tests in each folder.
Success is the ability to go from one failure to another with no loss of enthusiasm.
