How to configure TestComplete or TestExecute to only report Errors and change the log output folder

How can I configure TestExecution (or TestComplete) to only report Errors, (maybe also with screenshots) so that the logfiles at end get smaller as they contain only error relevant data.
Especially for Regression Tests I am not interested that pressing button x worked, but i would be interested if pressing button y does not work.
In the options I only found to disable the log files but no option to select what content the logfile should have. (but maybe I did not found that option).

And is there a possibility to change the default path where the logs are stored (without changing an environment variable)?

Thanks for support
