Сlassify your jobs using types.
Open Settings → Jobs → Types. Create new type by clicking on Add job type button.
Enter the name of the type in the new field. You can add any amount of job types you need.
Once you finish, click on Save button. If any field will be empty when you click on save, it will dissapear.
You can also change and delete any existing job type. But you can't delete type that is being currently used in the job or the job template.
Now when you create a job you can use created job type in the Type field.
