This morning I had a search results list of Logos products of which I wanted to add essentially all items to my cart. Unfortunately, there's no "add multiple" feature (i.e. using a checkbox); and clicking "Add to Cart" takes you to the "Cart" page, making it extraordinarily tedious to work through the items in a search results to add them to the cart.
I recalled that "Wish Lists" has an "Add all to cart" feature. So I created a wish list called "Virtual Cart." You can add items to a wish list without navigating away from the search results, so I added each item in my search results to the Virtual Cart wish list. It's still a bit tedious as you have to visit each item individually, click "Add to wishlist" and then uncheck / check the right wish lists. But it's significantly easier than navigating away from the page altogether.
Once I had added the desired items to my Virtual Cart, I went to the wish list page and added all the items from that wish list to the actual cart in one click.
FWIW...
