Change map mid scenario

Hi there. I discovered a mod with the wrong map setup in one of its scenarios. I figured out that to “edit” the scenario, I just have to go to the module editor and point it to a new savefile. But my question is can you edit map layout once a game has started, so I don’t have to entirely recreate the scenario using the New wizard, just to switch out one map board? Thanks!

Map if you set up it as a backgound of the map window is the sole fundamental thing in a save which cannot be changed via editing. It cannot be changed any way bur creating of a new file. Sorry.
