Re-playing a map

Is there any way that we can tell the game what seed to use when starting a new game? I started a game with the 1.4 beta and it's a great setup, but most likely I'll see something in the 1.4 release notes that I have to have and I'll end up abandoning the game. From the .err file:

Debug Message:  Map Random Seed: 1382296343

It would be great if there was some way to tell the game to generate this map again after the patch comes out officially.
