Do Hikashop support virtual product ??

I want a function like this page www.books.com.tw/exep/activity/promote/2...ty.php?id=PKG0025155

It can list all products in one category. The customer can choice the item.
If customer choise more then X , It will have another discount.

I think the reference webpage is to build another form. After Submit, it send a virtual combination product to the check-out module

Do Hikashop support virtual product not in the back-end product database for check-out ??
Or how can I do it??

Many Thanks!!

I have found my business version auto groupon can solve the price issue!!

Now I still lack of muitle checkbox to shopping cart funtion!!
