Ability to override Schedule Helpers

It would be nice to override the current state of a Schedule helper with a service call. The state would remain overridden until the schedule changes it. Something like:

Service: schedule.override
  Data: 
    Target: schedule.coffee_machine
    Status: On

Come on people, its a useful idea!

I’d really like to have the possibility to set up a schedule from an action. This would improve the interaction between automation and users a lot! Making it more clear for users on when things are going to happen, and even being able to override them if they don’t like the schedule for the day.
