Duplicate game removal to save space. Thanks

[Tommy1981]

Is there an import option that allows us to import games that are not already imported on other systems. 

For example. Say we start with adding all of the ps1 collection. Then we add the Saturn collection next. When the Saturn collection is being added, is there a way to add only the games not found in the ps1 collection. In addition, if we add the N64 collection, is there a way to only add the N64 games not found in the other 2 collections. 
 

thank you.

No LaunchBox doesn't store any strongly defined port information like that to determine that the games are the same across multiple platforms.
