In many schools the majority of subjects are Form Based, so we dont really need teaching sets. This option works well in Teaching Manager, where you can set a subject to be organized in Teaching Sets or by Forms. But then when importing a TT from ASC or KJ it does not import Forms. We work around this creating linked teaching sets for all subjects, but it would be much simpler to import forms directly from Timetabler software, so the Set Code would be interpreted as a Teaching Set if the subject is configured in sets or as Form if the subject is configured in forms.
