Answer

If you are trying to split locations into two sets or groups of locations, you can have a single set of locations, and you can choose which location goes on which map. For example, you can take one map which has the first group of locations for the current page, and you can have a separate map which goes on the second page which only contains the second group of locations. You can then easily move a location by removing it from the current map and adding it to the other map.
