Woocomerce - How To Link to Product Variation?

I am trying to find a way to have a link to a specific product variation.

I thought I had it solved with this plugin... http://ift.tt/1QJbCA6

However the I have 2 word product attribute names and can't seem to get it to work? I put _, -, & and + between the 2 words but not go.

Here is the doc...In my case I would have "color style" instead of just "color" http://ift.tt/1LYDO3Z http://ift.tt/1QJbCA8 (additional variations should be separated by '&') http://ift.tt/1LYDO41 (where the variation value is "Blue Green" with the space replaced by a '+')

Thanks!
