How to hide some products from WooCommerce store?

Question

WordPress

Hello, there is a very large catalog
. It has rulers
. And in order not to clog the store, I created a grouped product in WooCommerce based on the previously added ...
But how to hide products from the catalog that are already in the grouped product (with the ability to go to the product page from the group )? What not to litter the directory???
If it's too difficult, I'm ready to throw a little wood) but then write to [email protected]
Thank you)
