Substract stock only when set to a certain order status

I'm looking for an extension affecting the way stock subtract works.

Lets say an order is placed, and is created as "Pending". I dont want the stock status to be updated until the status is set to "Completed". The reason is that orders placed as e.g Cancelled (for different reasons) affects the stock status even when the order is not shipped, and will not.

Maybe set a certain stock status as disconnected from the stock status, eg. Cancelled.

Anyone seen a way to get around this?

I need help with the same thing as well. Things seem kinda slow around these forums :/

I also need help with this. Is there any option?

Thanks in advance.

From what I understand there currently is no option like this, or any correct stock control method for that matter.

I hop that in the next version this will be handled, since it's an issue which is quite important for most of us.
