Lists - duplicate childs for each list members

Hi, 

I'm working on a financial forecast model where sales is presented through 18 markets (Countries) to the 5 Products. So for example:

* Product 1

         - Country 1

                 |

         - Country 18

* Product 2

         - Country 1

                 |

         - Country 18

* etc.

 

I have made several lists with: Total Company (L1) -> Products (L2) -> Markets (L3).

Is it possible to make this hierarchy in the lists, where the (18) countries are the same, for each of the 5 products?

 

If not, what is the best practice to work around this problem and to be able to store the data on a Country/Market level for each product?
