[ic] Item made of many sub-Items

[Mohamad M. Hodroj]

Hello, 

Is there a way to create an item that is a combination of so many items...
what I need to do.. im setting up a computer company and I want to add an
item for a whole system. I want that item to be made of so many items (like
cpu, motherboard, hard drive and so on..) and I want it that whenever the
price of one item changes, the price for the whole system changes... is
there an option in interchange that does this for me or do I have to write a
script for it...

Thanks a lot guys..

Mohamad
