Great Features but you can't edit saved maps!

This seems like a fantastic plugin. Lots of features, easy enough to use, comes with great icons and it’s easy to have multiple locations. HOWEVER, you can’t really edit saved maps. I would need it for a very large map, with about 50 or more locations, which will eventually need to be updated. The fact that this plugin doesn’t allow for editing (other than manually editing the shortcode yourself) is pretty much a deal breaker.
