Instead of manually adding or removing products from each sub-site, use our WooCommerce Multisite Duplicate/Delete plugin. You can easily copy or delete products in a multisite environment using this extension. During duplication, you can prevent certain data from being copied. For example, you can prevent people from copying images, attributes, taxonomies (categories), or post meta.
Files can only be duplicated or deleted by network administrators by default. If you want regular admins or shop managers to be able to copy or delete products, you can turn this on. Additionally, bulk duplicating lets you copy multiple products at once.
