How to Link to product details page with specific option setting?

Tried to link hot items to their product detail page with selected option values, but I can only link to their product detail pages with 1st default options from cs-cart at this moment.

As you knew, when a product item have a color option, it may has different product codes, but not every color can be a hot item!

My problem is that when I show a hot item with X color, but the link to item detail page is 1st default color option , Y color. It looks like weird to customer!

Is there any way I can link to a product detail page with selected option values thru url parameters or other methods?
