I want to do a few things with the calendar

i want to do two thing in my calander,

i want to copy an event to an other calander “work backup” i want this to happen two weeks in advance (so i can see if some thing changes in those weeks) (i would like to get an alert if this is the case)

the other thing i would like to do is write an event in my calender if i enter a zone for more than 5 minutes and (bonus points if the start time is equal to the actual arival time) and close this event when i leave

hope some one can help me :slight_smile:
