You can change theme’s TownHub Add-Ons plugin -> Listing Type Builder element template from child theme by copy .php files from azp_templates to child-theme/azp_templates/ folder.
For example, you want to change contacts widget output on single listing page. And the widget’s template is plugins/townhub-add-ons/azp_templates/widget/lcontacts.php.
So you need to copy lcontacts.php file into azp_templates -> widget folder on your child theme then edit.
