woocommerce "Product Add-ons" order products on the CART page

Hi there,

I have products with variations.
e.g. t-shirt with sizes small, medium and large.

I’m using woocommerce 1.6.5.2 with WooThemes “Product Add-ons”.

The size select is mandatory.

Is there any way I can manipulate the cart page to group by Size.
eg.
Small———
t-shirt 4
jeans 3
Medium——–
hat 1
jacket 2
——————

So the variation is the Size, and I want the order of the cart to be by production variation “Size”.

Any ideas or suggestions would be appreciated.

Thanks,

Tania
