Shopify quick add to cart without taking customer to cart page

I am looking for some help with my Story Boxxe Shopify site please.

I would like to know if it’s possible to add a functionality/app to the products where the customer can chose from the products list page from 2 button options (on each item):

1) “buy now” (ADD TO CART) without being taken to the cart – like a quick buy option
2) “more info/customise” (which would take them into the product page to make changes and then add to cart

The idea of this is that if someone doesn’t want to customise the item on offer, they can add items without going back and forth into the cart and back. eg. The message cards where they can pick a few quickly and easily.
IF THIS ISN’T POSSIBLE AS I HAVE DESCRIBED – the next best option would be a little “buy now” or “quick add” or “add to card” button on items – which pops the item into the cart without taking the customer away from the product list page. Please.

Thanks
