How to make a discount on an Accessory for a product in Bitrix 1C?

Question

1C-Bitrix

Hey!
I use Bitrix and the Aspro Next store installed on it.
I have a product (let's say a Razor) and in its properties, as an Accessory, I added a product - Blades.
I want these blades to be discounted when this Razor is also in the cart.
Important! I have more than 30 such products with accessories. I need a universal discount that will apply to Accessories attached to the product. Any ideas?

In the cart rules, you can set discounts for different parameters with different conditions.
