Hi,
The maps are only generated from custom fields. The plugin doesn’t read the post title.
If you can copy the post title to a custom field when the post is saved, that might work. Then the map could be generated from that field. For example, copy the post title to a field called ‘address’.
That would require a little PHP. I think you could use this event:
