Auto add route distance into log without saving route

I find myself using route tracker not for saving routes all that much but for determining the distance of a route that I just did.  I don't save many of the routes I do because most of the time I go out and do something different because I'm bored with the same old routes.  I'd like to see the ability to add the distance automatically into my log for a route without having to save the route, like an 'Add Distance' button next to Dist vs 'Add New Route'.  I do this manually today but the convenience of adding the route distance on the fly would be cool, IMHO!
