Update stock when partial despatch?

We partially despatch orders on WooCommerce 2.2.10.
To do this, we switch the order status back to Payment Pending, edit the quantities on the order and then update the order and change the status to Processing. However the stock quantity does not update when we do this.

Does/could this plugin work to auto restore stock quantities, following the edits of orders in this way?

I.e.
With this plugin installed, would the stock refresh be triggered when an order is changed from Pending Payment, to Processing?

Many thanks
