Currently (Feb 2023) it is not possible to configure - and specifically to disable - the list-level "Import" option when creating new lists - i.e. whether via MyLists/New List, OR when instructors enter Leganto via LTI from the CMS/LMS/VLE (say BlackBoard) and are prompted to create a list. Currently there is no way to hide this option or control the types supported. This is inconsistent as it is possible to hide the option from the Section menu for example.
