There are three options to add a job to an existing group: From the list of jobs, from the details of the group or using the Duplicate button in a job.
From the list of jobs
In your list of jobs, you can drag and drop a job into another job (which already belongs to a group). When doing so, a green line on the left indicates in which jobs you can drag and drop the job concerned.
From the details of the group
Once you're in the details of the group (after clicking on the group in your list of groups), you can click on Add a job to directly add a new job to the group.
Using the Duplicate button
In your jobs that already belong to a group, you can use the Duplicate button to add the duplicated job to this existing group.
