Customer create a Bundle of items

Hello opencarters!
I was wondering if its possible for the Customer to create a Bundle of Items (of his choise)
For example :

Item - Price
1 - 5$
2 - 8.2$
3 - 9$
4 - 10$
5 - 7$
Bundle (1,2,5) - 15$
----------------------------------
I would like to give the customer the ability of creation his own bundle
like : Bundle (1,3,4) so i will give him some discount!

Moreover I would like to store this Custome Bundle (of my customer) in my database automaticly.
Extra : the customer will be able to few his bundle list , after his log in.

If this is possible, I would be grateful if you show me the way to it

If you search the store you will find very comparable extensions for this
