ok its pretty simple
this is the way i done mine

ok make a backup of bigmap.txt
and make your own txt file for your map like

"level1.graal","level2.graal"
"level3.graal","level4.graal"

then save it in the map as bigmap.txt
then create a lvl called onlinestartlocal.graal
and put this npc in it

if (playerenters) {
setmap map.png,bigmap.txt,playerx,playery;
}

then close down the NPC windows and hit M
then it should cycle through all of the levels and it will make your map
