I may have solved this with the below if anyone else ever runs into this issue. It is limited to affecting uploads only to a certain post type. Not sure if you could limit to only uploads via the gallery field somehow…

function add_filter_upload_image($attach_id){
$post_id = wp_get_post_parent_id( $attach_id );
$post = get_post($post_id);
if($post->post_type == <custom-post-type>){
$array = get_field(‘field_5f0dcbfc35af4’, $post_id, false);
if (!is_array($array)) {
$array = array();
}
$array[] = $attach_id;
update_field(‘field_5f0dcbfc35af4’, $array, $post_id );
}
}
add_filter(‘add_attachment’, ‘add_filter_upload_image’, 10, 1);
