Modifying a preset

You can adjust the settings and field values in your custom presets. You can't change system presets, but you can duplicate them and modify the duplicate, as described in [Creating a preset, based on a system preset](create-custom-preset-from-system-preset.md).

After you modify a preset, jobs that use the preset will run with the new settings, including the following:
+ Jobs that directly specify the custom preset.
+ Jobs that you create based on a template that uses the custom preset.
+ Jobs that you duplicate from your job history that use the custom preset. The original job used the settings in the preset as they were at the time; the new job uses the current settings.
