Ability to control meeting outcomes via workflow

Our sales team has back to back meetings all day long and would love the ability to automatically change Meeting Outcomes based on the meeting time passing, in a workflow. This way, they would only have to worry about changing the outcome if they didn't answer, show up or they reschedule. 


We would like the default Meeting Outcome to be Scheduled/Completed. This will also help them keep their reporting more accurate, just because they have so much they are constantly doing.
