Exclude Items in My Collection from Buy page and Games list

Exclude My Collection from Buy page and Games list

I would like to exclude any games already in my collection when I browse the Buy page and a Games list page.

My two use cases:

Show me all <system> games for sale that I don't currently own on

https://www.pricecharting.com/search-products?q=&sort=name&console-uid=G17&genre-name=®ion-name=all&exclude-variants=false&stock=in

Show me all games in the Games list that I don't currently own on
