Simple product with attributes and quantity

Hi, I was wondering if it is possible to create color selection and quantity entry options for each chosen color in a simple product.
I currently have this situation of a variable product: Headphones, colors: Red and Blue, my client wants to buy them and wants 30 reds and 30 blue ones, then he chooses the color and quantity for each color, then the cart updates and shows individual items like:
– Headphones, red = 30
– Headphones, blue = 30
The cart calculates the total price as individual items. I offer wholesale discounts from 50 items. This discount will not be calculated because my customer has 2 items, each 30 and not 50. Even if my customer has purchased 60, my discount will not be applied because they are separate items and none reaches 50.
What I am looking for is that in a simple product I can have these color selection options based on attributes or on options created.
Thank you.
