WooCommerce display Stock next to Variation name in dropdown

Using WooCommerce, I am trying to find a way to display the stock level for each variation, next to the variations name in the dropdown.

eg. http://www.kynetonfoodstudio.com.au/product/good-morning-vietnam/

In the DATE dropdown, I want to show the variation name which is the date, followed by the stock level... eg.
Saturday 3rd September, 10:30am - 8 SPOTS LEFT.

Can anyone point me in the right direction?
