Here is one such map:
It has as many as 5 zones for cutscenes: top left, top right, the center with a lake, bottom left with a pillar, and bottom right with stones.
The top left zone is used in the first cutscene for Raileigh, and the other zones are used in the campaign featuring Agrail against the elves.
So, my point is that one map can have many locations for other cutscenes, and you need to be careful when editing it.
