Amazon Shipping Templates in Shipping Rules

I would like to be able to specify an Amazon shipping template as part of the shipping rules in SF. Currently all orders for standard shipping have the channel shipping method of STD UK DOM_1. If I wanted to use two shipping templates, one which offered 2-3 working days as standard and one which offered 1 working day as standard both of these still come into SF as STD UK DOM_1 and are impossible for SF to tell which is 2-3 and 1 working day. Having an option within the shipping rules which allows you to specify by shipping template would mean I could offer different levels of standard shipping on my Amazon listings.
