WooCommerce ID can be added as a Column on your Items Search to show you Links.

WooCommerce ID helps identify the Products on your WooCommerce that are linked. Set Update Pricing and when the Item Price changes, the WooCommerce price changes.

You can Find, Sort, and Filter--enter a Hash mark for Not Equal To blank--to see IDs. If there is an ID, that is the Product that will get automatic updates for price or count.
