Console line scriptable control for Test Runner.

When I make Test Runner tests I often added Debug.Log messages that more or less report the details of the test should I decide to run a specific test and look at them. Some 'reports' that I send to the console via Debug.Log messages I would like to show one line. Others I would like to show 5 or 6 lines. I would really love it if I could adjust the console option that sets the number of lines shown from a Test Runner script. I am not seeing any way to do it but maybe I am missing something.

Edit: It also seems like the setting of the number of lines shown is global. While if it were scriptable it would be great to be set per Debug.Log call.
