How to add dynamic attribut on each items of the Cart ?

[mrdan]

Hi everybody,
It's the first time I post. I don't find any answer of my question on the forum.
I must develop my own module in compatibility with Prestaphop.
I want, when a visitor purchase a hosting plan, he chose his domain, and the domain he chose must be viewed in Cart and Orders.
Example in the cart page :
----------------------------------------
Item 1 :

- REF : HOSTING100

- Description : One year hosting 100 Mo

- Domain Name : mydomain.com <-- this is what I want to add

- Price : 20$

Item 2 :

- REF : HOSTING500

- Description : One year hosting 500 Mo

- Domain Name : myotherdomain.com <-- this is what I want to add

- Price : 40$

-----------------------------------------


So the question is :
What is the best solution to add this dynamic attribut (Domain Name) in each item of the cart and the order ?
What hook can I use to display other informations un each item ? shoppingCartExtra ?

If it's possible, I think it's better if the customer chose his domain before he click on ADD TO CART, like combinations.
But how to do this ?

Thanks for the answers
and sorry for my english
