Possible to make a combination unlimited?

[anth.payne]

I want to beable to make a combination unlimited?

I.e, as long as there is stock of the core product, anyone can order the combination?

What i'm seeing at the minute is the combination qty's are cumulative...

I want to beable to have the core product with no combination added, (e.g, with 10 in stock), for which i need to add a combination of none to achieve. Then, for example, you have a combination of Hard Drive, which for every core product in stock, you can add the hard drive. but if i add a combination of 10 hard drives, you get a total cumulative QTY of 20.
