Shop like Dell website

-- url of the page with the problem -- : www.assistenzainformatica.tv/shop.html
-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.3.26

I bought Hikashop business, I would like to create a computer shop in my website where you can customize a PC similar to the Dell website.
I would like to start from a basic PC and then customize it, for example to choose the processor between processors loaded as items including description, without having to load new items and with the possibility to enter a discount on the price.
The same applies to other components such as RAM, hard disk, etc..
is it possible?
Thank you.

I've already done with the options but I have to reinsert the items (eg, processor, hard drive, etc.). While I wish I could insert existing articles with their description.
