In Jira Product Discovery there's a field called Goal ("The goals this idea helps the team achieve") and there seem to be some built-in options: "Learn this tool" "Increase revenue" "Win enterprise customers" "Delight users" "Become a top rated product' and "Expand horizons". I can select one of those pre-existing goals, but if I go to Field settings and Search options, there's no option to set my own custom Goals to assign to ideas. Am I missing something? Is there a way to add my own custom Goals for the Discovery project?
