manually adding awx manage jobs

Hi,

Is there a way to add the awx management jobs to a existing installation of awx? If one installs one of the newer version of awx (after 6.0) there exists management jobs in awx for cleaning logs. If one migrates, these jobs are never added. Is there a way to manually add these jobs to an existing awx migrated installation so that they can be used. currently when I go to management jobs in my migrated 13.0 awx, there are 0 jobs. In a new 13.0 installation there are management jobs under that tab/selection.

Thanks,
Michael
