QA ISO test tracker does not allow 'started' to be changed

During testing of the development/pre-release ISO images, the QA tracker at http://iso.qa.ubuntu.com/ allows the individual to mark a test as started. Unfortunately, once the test is marked as 'started', the only options available are 'failed' or 'passed'. If I mark the wrong test started, or mark any test 'started' and find I can not complete the testing, I can not unmark the test.

While I do attempt to insure I am only marking the test I can do, if I do mark the wrong test as 'started', I can unmark that test (and mark the correct test). There needs to be a provision to unmark the 'started' box, even if that is limited to the release supervisor or testing supervisor for that release.
