Ability to list product variants on Catalog Page with Add to Cart

I would like to be able to add variants to the Catalog page like I can to the Category and Catalog Search pages. What I want to be able to do is have a customer who already knows what they want not have to navigate to all the products, but to be able to go the Catalog page, select the product quantities and variants on one page for all the products they want and then press Add to Cart once.
