Answer
- If you have not edited and saved your actual map, then no problem. Just go back to the event, enter the address and save. Next time you open the map it will open at the address you just entered.
- If you have already edited and saved the map, then the map location is saved as is. You can still go and edit the address in the event, but this will have no effect on the map itself.
- At any point you can select all the items on your map and either moe them to a new location or delete them, then move to a different location on your map and start again.
The bottom line is that once you have saved your map once, the location of the map and the address of the event are independent.
Happy Mapping.
