Is there anyway to turn of Time, Pid, Thread and Severity, need the space?

Hi big fan of the gem but due to the volume of logs I need to fit more information onto the first line of the log as shown in cloudwatch. As cloudwatch already logs the time and the other automatic fields are not useful to the information I want to log I was hoping there was a way to turn them off?

many thanks, Simon
