Price override for addons and upgrades
When placing an order for a product through the API, you can only supply a price override if the order is for the main product. I would like to be able to override the price for an addon as well please.
I would also find it very useful to be able to provide a price override when upgrading a product for a client. As far as I can see, it does not read in the 'priceoverride' parameter.
