Kits in Order Management

Hi Gurus,

We have Kit item AB with gift items A and B in it. When the kit is ordered, there should be an option to select A or B or both (just like Item relationship screen in sales order).

I cannot use Promotional goods as it will auto populate all the get items.

I cannot use Item relationships because the gift items A and B should be 0 priced. But if the gift items A and B are ordered independently (not via Kits), they should have price from a price list.

Is there a way to achieve this?
