Can we get a feature added in the future, where it will route on toll roads if it saves a certain amount of time?

Tolls in my area and for my drive can rack up nearly $20. Totally worth it if it saves me 20-30 minutes, but if it's saving me 2, I don't really want to be re-routed.

I don't want to turn off Tolls, because it IS worth it to me to be given the option, but I want to be able to set the threshold of how MUCH time does it need to save me to shell out the $.

Thanks!
