Add a step to WooCommerce Checkout - wordpress

Question

Is there any way to add a new step to the Checkout process in WooCommerce? I need something between the cart and the Billing Details page to collect some additional information. I've researched quite a bit and turned up nothing. I can't be the only person who wants to do this.

From my tutorial on WooCommerce Custom Checkout Fields this is how to add a custom checkout field which you could use to collect additional information.
// Add a new checkout field
function kia_filter_checkout_fields($fields){
$fields['extra_fields'] = array(
'some_field' => array(
'type' => 'text',
'required' => true,
'label' => __( 'Some field' )
)
);
return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'kia_filter_checkout_fields' );
// display the extra field on the checkout form
function kia_extra_checkout_fields(){
$checkout = WC()->checkout(); ?>
<div class="extra-fields">
<h3><?php _e( 'Additional Fields' ); ?></h3>
<?php foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) : ?>
<?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>
<?php endforeach; ?>
</div>
<?php }
add_action( 'woocommerce_checkout_after_customer_details' ,'kia_extra_checkout_fields' );
// save the extra field when checkout is processed
function kia_save_extra_checkout_fields( $order_id, $posted ){
if( isset( $posted['some_field'] ) ) {
update_post_meta( $order_id, '_some_field', sanitize_text_field( $posted['some_field'] ) );
}
}
add_action( 'woocommerce_checkout_update_order_meta', 'kia_save_extra_checkout_fields', 10, 2 );
// display the extra data in the order admin panel
function kia_display_order_data_in_admin( $order ){ ?>
<div class="order_data_column">
<h4><?php _e( 'Extra Details', 'woocommerce' ); ?></h4>
<?php
echo '<p><strong>' . __( 'Some field' ) . ':</strong>' . get_post_meta( $order->id, '_some_field', true ) . '</p>'; ?>
</div>
<?php }
add_action( 'woocommerce_admin_order_data_after_order_details', 'kia_display_order_data_in_admin' );
