I need to allow multiple size selection (bulk) of a variable product in WooCommerce

All I need is the ability to add multiple SIZE variation of a selected product variation (for example a Blue Gildan 5000 t-shirt). I have linked a mockup of what I like to see, and what it looks like now. In vanilla Woocommerce, you can only add-to-cart a single product variation (1 colour, 1 size) at a time. There is a plugin by Woocommerce to allow bulk add-to-cart but it's not very intuitive (can possibly be modified? -see note2). ----Example: Requested functionality (mockup): [login to view URL] Current functionality: [login to view URL] Link to product variation example used in mockup: [login to view URL] What would this cost to make (into a plugin or other form of implementation)? ----Note: I use a plugin called "WooCommerce Extra Product Options", which allows me to have extra options per product that also replaces the default price value to allow customers to see the final price in real-time before the customer adds to cart. ----Note 2: I tried to WooCommerce's official "Bulk Variation forms" plugin, which sucks ROYALLY. I have it enabled for you to see. Basically, it allows you to bulk order, but instead of being embedded for some reason it's a button that hides the whole page and shows a table with text boxes of all the product variations. Ideally, we don't want the customer to click unnecessarily just to order bulk. It should easy to view and just be a table embedded right before the "Add to Cart" button. This is just some info in case you guys were curious. ----Link to WooCommerce Extra Product Options ([login to view URL]).
