Influence Automatic Interface Metrics Assignment

is there a way to influence the automatic metrics algorithm (interfaces and per IP) in some way? Influence in the sense of manipulate.This problem also covers following posts: "multiple NICs; automatic metrics" "Two NICs with identical gateway metric" Very often there are several default routes but with different metrics. In most cases automatic metrics algorithm works fine, but there should be a better way to switch the "Default Gateway" other than setting manual metrics for each belonging Adapter (and IP). There SEEMS TO BE a promising way to control automatic metrics assignment. There is a control panel dialog: "Control Panel -> Network Connections"

If you click ALT key on your keyboard here, and then selects menu "Advacned -> Advanced Settings..." a dialog is opened where you can change the order of Connections in the "Adapter and Bindings" tab. No one knows the purpose of changing the order here, but I expected to influence the automatic metrics assignment which would make sense. But changing this order will NOT change any metrics. Is this a bug in Windows Vista or does this order have another purpose? Is there a way to change this automatic metrics assignment in some way? Are there some information (released by Microsoft) that shows the algorithm for automatic metrics assignment? I need this information because I'm currently developing a small Windows tool to simplify the "Default Gateway" selection. My current tool still lacks of some features and don't work as expected.
