HighendWP child theme and customizations

I created a child theme for HighendWP. I needed to MANUALLY redo the menus in the child theme. I then find I have to reset virtually all the colors under Customize.

Is there anything else I need to manually coordinate between the parent and child ?

Is there anyway to setup the child theme so that I don’t have to manually change these ? I thought the point of a child theme was to avoid the need for this duplication of effort and monitoring.

functions.php

<?php
add_action( 'wp_enqueue_scripts', 'load_parent_styles_when_child_active' );

function load_parent_styles_when_child_active() {
if ( is_child_theme() ) {
wp_enqueue_style( 'HighendWP-style', get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'HighendWP-child-style', get_stylesheet_uri(), array( 'HighendWP-style') );
}
}
