Can I save preferred route as favorite?

I have chosen a destination with an alternative route as that is the way I always wish to go - but I do not seem to be able to save this route as a favorite as I keep being asked each time I select the favorite whether I want fastest route, shortest route etc. Anyway around this? TomTom XL. Thanks for any advise. This is just the beginning - I am sure I'll be back!

You can preselect which type of route you want, but not tell the device which route you wish to use always.

You can only save locations as favourites, not routes.
