C19 Wishlist, create alert, ignore and own games by groups? is about adding similar "select all" and batch processing feature as in Collection or Wishlist - it will be added to all lists, including public lists (if/when we add them).
You may also take a look at custom lists aside from alerts and wishlists and linked requests, and share your use case there - it is easier to handle feedback if we gather it in 1 place.
