Apache mod_index configuration (apache expert)

I need to configure Apache (2.0) using FancyIndexing (mod_index) so that the "Parent Directory" link doesn't appear *above* a certain level in a directory tree. In other words, "Parent Directory" (the default link) appears in every subdirectory of a given tree, but not in the specified root directory. IndexIgnore is an apache / mod_index directive that inhibits display of certain files / directories, and: IndexIgnore .. works at preventing the "Parent Directory" link from being displayed at a certain point in a tree *and below* (because the directives apply to all subdirectories). I only want it at *one specific* directory. I *think* this can be done using existing 2.0 Apache directives, but I haven't been able to figure it out. It's worth $150 to me.
