Can a Leganto reading list be attached to multiple courses?

A reading list can be associated with multiple courses in Leganto.

To enable multiple courses for reading lists:

Set the parameter multicourse_lists in the customer parameters table (Configuration Menu > Fulfillment > Leganto > Customer Settings) to enabled.
Selecting Associate this list with a course on the Course's Reading List or Reading Lists Task List pages opens the Courses tab on the Edit Reading List page.
Selecting Remove associated course on these pages opens the Courses tab on the Edit Reading List page ONLY if there are multiple courses associated with the list (so that you can select which one to remove). If there is only one course associated with the list when you select this option, that course is simply disassociated with the reading list, as usual.

For further information, see the documentation on Managing Multiple Courses for Reading Lists, found here.
