Modifying the output of class-geodir-widget-post-title.php

I need to modify the output of the title/link on GD Archive Item template so that it doesn’t output a link for particular package_id’s

My V1 site used conditional logic like this, in the listing-listview.php template and in a function on for the detailed page:
IF ( $post->package_id != ‘6’) { //do something }

How can I apply similar logic to the output of the [gd_post_title tag=’h2′] shortcode? I found this filter: geodir_widget_gd_post_title_tag but that’s not getting me what I need. Is there a hook? Thanks.
