Planned arrival time

It would be very nice to have the option for plans (saved plans) to set the option when i want to be at a goal (sorry for my bad english, but i am sure you understand what i mean). Next level of this option would be to select different options like: be at about XX minutes earlier there, also get a notification on the phone at for example 30 minutes before departure time, when it would be time to start travelling aso… and please - easy to find this option - not as complicated as save plan / when will i start driving… 😡
