Does anyone know if I can go into the Tropico 4 and modern times campaigns and make them more difficult to do such as raise the requirements for finishing objectives like needed 10,000 in treasury changed to 1,000,000 or something like that?

I would love to replay the campaign again but its just so damn easy after playing through both campaigns, also I'm not really into sandbox because I'm not good with a lack of objectives(plus its too easy to just simply build a thriving country in sandbox mode too).

Thanks
