Singleplayer Campaign - Handicaps

Hello
i would much like to be able to use the handicap setting in singleplayer campaigns.
this is already kinda possible through the coop campaigns although, that of course only affects maps and campaigns playable in coop mode. most campaigns are not and have therefore no handicap settings.

Oh yes that would be cool.

That would also help smoothing the curve between the different difficulties.
Like Going from Medium to Hard but with 10-20% Handicap.

I think they should also add the comfort features like Auto Economy from the Xbox version to PC too for those who want to enable it in Single Player.
