Question
It is possible to create a script field on general preference using a script.
But can we create a field group to add this script field under that?
If yes, please advise how to do this?
Answer
Field groups in the Custom Preference of General Preferences are the Bundle name of where the custom field came from. This is not customizable. You may submit an enhancement request for it but make sure to be specific in the details when submitting a request.
