The company that I work for is building just such a product for you. It is an add on to MP and among other things it would do what you are asking for with regards to routes. We are looking for beta testers. Please email me if you are interested, at johnwhirl@yahoo.com . if you are not interested in a beta version starting on June 3rd you can download the product for purchase. I will post a link to the product purchase page at that time.

Regards,
John
