The d2l.Tools.Grades.ExportHandlerPage config variable enables the 'Export to SIS' button on the gradebook. Does D2L provide a default page for the export handler OR is this always a custom developed page by each client. The description of the config variable states "The value can be to an internal page such as /d2l/lms/grades/admin/enter/exportSIS.d2l?ou=6606&otherparam=othervalue" - is this just an example value or is this a provided page?
