Create product packages

-- HikaShop version -- : Business 3.1.1
-- Joomla version -- : 2.5.28


Hello

We are a retailer offering a product package to our customers. We would like to offer a seasonal package containing several items and different options for some of them and present this in a way they can only select this item. It gets more complicated since we have some products like men/women pants plus the size option and having a dropdown menu does not seems possible.
The price is fixed, that means we can't use the same price published on the website, for what I heard hikashop does not allow to have 2 dif. price for same item code.

The package will look similar to this:

Pack price $100
Item 1: offered in 2 size options
Item 2: its a pant option, first selection waist then then select sizes. Plus the pack includes 3 units of this item. Not sure how to solve this
Item 3: Shirt first selection men/wom, then select sizes.
Item 4: 2 options


I don't see a clean way to create the pack, can you help.
