Add a "Add More Products" Button to the "Cart Popout on add to cart"

This is for Non-Savvy customers. Currently, if I've toggled the "Show the cart popout on add to cart" option on, I will only see 2 buttons "View cart" & "Checkout". The problem: On mobile, as the cart popout takes over 7/8 of the screen, it is left with 1/8 of the screen for customers to go back to the product selection page. In the case of variable products, customers may want to buy multiple product with different variations, so the customer may think that they have to do multiple purchases to get all the product variations they want. But, with a simple button or link on the cart popup, it will prompt the customer to go back and select more, instead of view cart or checkout.
