Product bundle / 2 and more Products with one clic

-- HikaShop version -- : 2.3.4
-- Joomla version -- : 3.3.6

Hello everybody and merry xmas!

I am facing a problem ... i am using the "add to cart" html link.
Now i want and have to to the following thing.

When i click the button, it has to add 2 products at the same time.

Is it possible to do something like that?
Can i type "http:/...option=com_hikashop&ctrl=product&task=updatecart&quantity=1&checkout=1&product_id=2-AND-ONE-MORE"?

Thank u very much!

a friend of mine made a great workaround with JS.

If there is any solution in hika, it woould be nice to know. if there is not .... no problem

Thanks and merry xmas!

Thank u very much!

Now i am facing one more problem with the add to cart link.
If i want to add the same product to the cart again, the qty is still 1.

Thanks
