Hey John,
You can likely use the hooks for this.
For example, if you had a custom field for each post, you could output that field like this:
add_action( 'wpsp_before_content', function() {
$text = get_post_meta( get_the_ID(), 'your_custom_field', true );
if ( $text ) {
echo $text;
}
}, 20 );Let me know 🙂
