The 'name repeater' value works the same way as the 'Course full name' setting, except that it will be repeated for each member course in the crosslist, and the 'name divider' will be placed in between subsequent repititions.
The name repeaters can contain the same flags as 'Course full name'.
In addition to the standard flags, 1 new flags is added:
Example: Say you have two courses, 12345.200710 and 54321.200710, and they are crosslisted with the crosslist code XLSAA200710. If you set 'Crosslisted course full name' to '[XLSID] - [REPEAT]', 'Full name repeater' to '[CRN]', and 'Full name divider' to ' / ', the resulting full title of the crosslisted course would be 'XLSAA200710 - 12345 / 54321'
