Open your map.wz.

Go to the map you want to release and click it (<mapid>.img Example: 910000000.img).
Now click XML>Dump>Storage\distribution purposes>I want to create multiple XMLs>Dump.
Go to the folder and upload the XML.
Now to import one of these XMLs ...
Open your map.wz.
Find the XML you want to import.
Look at the file name. If it starts with a 0 (maps that start with 0 have an ID less than or equal to 99,999,999), click Map0 folder in the map directory of your wz. If it starts with 1 Map1, 2 Map 2 and so on ...
Now that you clicked the Map<number> click XML>Import>Find your XML
Now save that map.wz.
