mute a test

 Here is the scenario: 

User A broke a test and he muted the test so the build doesn't show failure. The test status showed that UserA is the one who muted the test. This is all good. Later User A fixed the test so the test is automatically unmuted and passed. However in a few days User B broke the same test again, I noticed that TeamCity automatically muted the test again and it still showed that UserA instead of UserB muted the test. Is there a way to disable this automatic mute functionality? When User B broke the test, I want the build to be failed so that we know that the test is failed and it is failed by User B.
