One of the things I have not been able to fix has to do with course/folders/mailboxes names which, by default use courses fullnames.

Nevertheless, since our courses have really long names, it would be much more practical for us to name folders/mailboxes using courses shortnames (both in the skicky block and in the list of folders within the general mailbox).

My questions is: Is there any easy way to change that. Could you please tell us where this particular configuration is setup?
