Hi
How to remove the price of variant products by using the action button at the top of the back-end Product List?
I usually select the "update the values" to change the price from the action field, then select price_value from the next field and enter the desired amount.
But now I want to remove the cost of the variant product to get the amount from the original product.
When I zero the value using the action button, the amount is 0, which means the product is free. The amount of empty does not accept.

Can I enter multiple product IDs instead of running this command multiple times with different {product_id}?
