Possible to move your party around the maps?

When playing the original all those years back, I recall using an editor (or something similar), that let me change the position of my party even to maps I had not yet explored. This way, it was possible to go fetch all those NPC:s that are normally not available to you early in the game. Then you simply repositioned your new party at one of the early areas and played on. Anyone remember which editor that was? Was that feature part of GateKeeper but then removed in ShadowKeeper?

MoveToArea("ARxxx");
command should do it will do it, but you need to know the area code.

lists the area codes for all the original BG areas (I assume BGEE uses the same numbers for those areas)
