[Map] Creating & Inserting New Maps In AdvancedMap

Hey gang. Can anyone give me insight on creating new maps in AdvancedMap. Each time I do it in Advanced Map my new map is automatically put into the same category as a preexisting map or requires I select it to be grouped with a pre-exisiting map. I cannot find a way to name my new map without renaming the map its grouped with. How do I get around this. Am I missing something? I am using AdvancedMap 1.0.9.

To my knowledge, the only way to have a custom name is to rename the unused ones
EG: emerald = seveii isle 22

That means that you have a limit of maps you can create based on the names available? That sucks.
