the limit on gold (Foundation)

Hi all, here's the problem: there is a limit on the 500 gold. For tasks (sending troops) give 1000 gold, but the run is only 500, the rest is burned. Profit from public for a week out more than 7 thousand, but again, due to the limit of 500 gold cannot develop normally.
Now the question is - is there a possibility how to edit the game to set a limit of gold, say 100k, for a start?
