Add meetup time in calendar#434

Be able to set a meetup time to a match , so you have the time in the calendar.

Ex i have a match at 12:00 but need to meetup 45 minuts before, so the actuel time is 11:15.
So the 11:15 should be added to the calendar as ex. “Preparation time”

Great idea! +1

along with the function to add travel time?
