Save default attribute for customer

[XSized]

I'm looking for a extension that allows customer to save their default attribute. 

Let's say: customer loves the color red so he will always buy a red product. So he have to choose the product, click on red and now he can add the product to cart. Same for next product and so on...

I would love to see that customer can save the color red as his default selection so every time he add a product to cart, "red" will be selected automatically and added to cart.

You will have to build a custom extension for this feature. I am not aware of a module that will do this
