How to redirect to specific product variant using bundle app?

[Bumpyshot]

Hey, I'm using a bundle app, on my landing page I have a section with a swatch selector, I want people to be able to click on a color and be redirected to the product page with the color/variant selected. So i have created a special link with ?=variant when people select a swatch but when they are redirected to the product, suddenly the url switch to the default variant... Any idea? I'm using wide bundle.
