Editing Places and Events and Custom Tags

Hello all.

One thing I think might be missing from this great app, is the ability to edit your already existing places and events and custom tags... what if for instance you mislabeled a place "Neu Yorc" and then you need to go back and edit 40 momentos just to put "New York"? I mean it's great we have the chance to add new places, but I wonder where is the edit button?

Thanks for your time.
