At least once
If the rule applies, the item is in the cart at least once, even if there is no matching product. If you do not want that, include the products in the rule, for instance with Item in dynamic product group.
Without further settings an item is added exactly once. When linked, its quantity follows certain products: one wrap per piece, one surcharge per bulky cart line.
On the Quantity tab you switch on Link quantity to products and choose which products count: individual products, dynamic product groups or tags, or all of them together.

On the right the same cart, both times with the bulky goods group: two sofas and one table are bulky, the cushions are not.
