Nested each in shortcode

Hello,
I’m using shortcode display values from relationship field images, and I would like to display their relationship field as well. It semi-works, but values are duplicated.

My code:
```
[each linked_car]
 {@linked_car._img}
 {@post_title}
 [each linked_car.sub-color]
   {@linked_car.sub-color._img}
   {@post_title}
 [/each]
[/each]
```
"linker_car" field is a relationship field (file/image/video) of my pod called “cars”

"sub-color" field is a relationship field (file/image/video) that extends Media content type

The shortcode above works if there is only one value for "linked_car". However, if I choose multiple values (images), all sub-color values are duplicated for each linked_car entry. Using nested each without "linked_car" part doesn’t show anything.

Is there a way how to display "sub-color" values only for their correct and one "linked_car", and not for every entry?

Field name within [each] should not be repeated as a field prefix within the [each] like {@linked_car.xxx} within an [each linked_car]

[each] template tags cannot be nested due to the nature of templating shorthand.

For more complex logic available in a full programming language, such as nested loops, use add_shortcode() or PHP templates.

[linked_cars]

<?php
/**
 * Plugin Name: Linked Cars shortcode
 * Description: <code>[linked_cars]</code>
 */
 add_shortcode(
 	'linked_cars',
 	function( $atts, $content, $tagname ) {
 		ob_start();

 		foreach( (array) pods()->field( 'linked_car' ) as $linked_car_id ) {

 			// https://docs.pods.io/code/pods/find/
 			$car = pods( 'car', $linked_car_id );

 			// https://docs.pods.io/code/pods/template/
 			echo $car->template(
 				null,
 				'
{@_img}
{@post_title}

[each sub-color]
	{@_img}
	{@post_title}
[/each]
 				',

 			);
 		}

 		return ob_get_clean();
 	}
);
