How to make a variation in Woocomerce per item?

Question

WooCommerce

Hello, the question is, is it possible to implement this in Woocomerce? The point is that you need to make variations with packages, as in the screenshot and individually, all this can be done, but the question is about the additional checkbox. We just did it additionally through the booster, but here it’s the price per unit of goods, that is, I indicated 3 products and ticked the Hi-float checkbox and 30 rubles were added to the amount, also with variations above, if I choose 20pcs, the price is 850, I’ll put tick the price will be +200 rubles (the price per piece is 10 rubles), please help with advice.
