Edit Woocommerce cart

Hi

I know this is off-topic, but hoped someone knows a snippet how to do it.
I am looking for a way to allow editing in Woocommerce shopping cart page and checkout page.

Example: The customer selects Blue from the drop down and adds the product to the cart.
The customer goes to the shopping cart or checkout and decided to change the color to green. Instead going back to the product, i need the option under the cart and checkout.

Thanks

Edwin
