You could modify MARCXML plug to add the starting letter as the first
part of your subject hierarchy, for example "A|An Example|Subject"
instead of "An Example|Subject".
This would give you a vertical A-Z list as the first level. If you
wanted this to be horizontal instead, specify the "-hlist_at_top" option
to the Hierarchy classifier.
