Edit the map from a savedgame

[skanibal]

Hi guys,

Here is my problem, I spend hours on factorio during my holidays, but now office is taking my whole time.
I know it's absolutly cheating, by i'm looking for a tool to edit the map from a savegame as it is when i saved the game (with belts, buildings etc...)
Do you guys have a stuff who allows me to do that?

Thanks lads!
