I wonder if exists a snippet or maybe a plugin that just adds a metabox in woocommerce categories to add an extra cost to the price (not at cart) for all the products of that category. Can you help me?

Add Extra Price dynamically from categories meta

Steps:

1. Add extra price input fields on product category add / edit
2. Save product category extra price input fields
3. Optional - Show/List extra price column on the category listing(table)
4. Finally - Add category extra price into categories products( assign product)

Code:

        <input type="number" name="extra_price" id="extra_price" maxlength="4" value="0" />
        <p class="description"><?php _e('Add extra cost to the product price', 'woocommerece'); ?></p>
    </div>
