Unable to change the app-name / programname for barbican-api service

Hi guys, I am facing issues with barbican-api logging with syslog. I have configured rsyslog for barbican service and want to write the logs on remote host based on %programname properties, but i observed barbican-api app-name is not set ,so by default it's logging into loadwsgi.py.log . I s there any way to set the app-name for barbican-api service ?
