Hi flantascience. Yes.
I used this code in functions.php

add_filter( 'wpsl_store_meta', 'custom_store_meta', 10, 2 );
function custom_store_meta( $store_meta, $store_id ) {    
    $terms = wp_get_post_terms( $store_id, 'wpsl_store_category' );    
    $store_meta['terms'] = '';
	if ( !is_wp_error( $terms ) ) {
		if ( count( $terms ) > 1 ) {
           	$store_meta['terms'] = get_bloginfo('template_directory')."/images/icono-multimarca.svg";
        } else {
			if (function_exists('z_taxonomy_image')) {
            	$store_meta['terms'] = z_taxonomy_image_url($terms[0]->term_id);
			}
        }
    }      
    return $store_meta;
}
function custom_frontend_meta_fields( $store_fields ) {
	$store_fields['wpsl_terms'] = array( 
        'name' => 'terms'
    );
    return $store_fields;
}

Note that you need to install the plugin Categories Images and assign an image to the categories.

I hope it helps!
