Yes, you can duplicate any job you want using the Duplicate button at the job level. 

You can use the Duplicate button to add the duplicated job to a new group or to create a dependency. (If the job you want to duplicate already belongs to a group, you will also have the possibility to add the duplicated job to the group.)

If you choose to duplicate the job alone, the system will then ask you who's the client for the copied job and the name you want to give to this new job.

If you choose to duplicate the job and create a new group, you will be asked to define a name and a service for the duplicated job.

Then, once in the duplicated job, you will see (on the left under the job name) that a group has been created along with the duplicated job (you can view the group details by clicking on the name of the group).

If you choose to duplicate the job and create a dependency, the duplicated job will become a dependency of the job you're duplicating.
