Modifying the gd_single_tabs Shortcode

Hello, GeoDirectory –

I had my site configured so that only local residents can see the ratings and reviews for our businesses.

I had this set up in GeoDirectory V1. Here is a link to the support ticket I submitted back then:
https://wpgeodirectory.com/support/topic/inserting-a-shortcode-into-the-review-area/

In V1, I edited the “reviews.php” file to add some code to check for the user’s residency.

But I need to know how to do this in V2.

I’m currently using the following code on my Listing Details page:

[gd_notifications]

[gd_claim_post text="Claim this Listing" output="button"] [gd_author_actions hide_delete="1"]

 

[gd_post_images type='slider' ajax_load='true' slideshow='true' show_title='false' animation='slide' controlnav='1' ]
[gd_single_taxonomies]
[gd_single_tabs show_as_list="1"]

[gd_single_next_prev]

 

Recently Viewed:

[gd_recently_viewed post_limit="4" layout="gridview_onefourth" post_type="all_post"]

So I think I need to modify the shortcode [gd_single_tabs show_as_list=”1″]

Where can I find the source for that shortcode, and how to I update it as a child plugin, so that it won’t get overwritten at the next update?

Thank you
James Grove
