Set explicit dates to schedule

It would be very helpful to have specific dates in the scheduler. If I'm going on a planned trip, I would like to be able to prepare the car in advance - set higher charge level for the nightly charge before etc. If that trip is more than a week ahead, this isn't currently possible. It would be helpful to be able to specify the date explicitly for trips further ahead. 

Taking this a stage further, what would be even better would be a "trip wizard" whereby a (configurable) sequence of steps could be specified and the wizard simply asks for the date and time of the trip, eg

• Set higher charge level before the charge on the night before
• Turn on HVAC x mins before the departure time
• Return to default charge level before next charge
