Yes, under the difficulty settings when you start the campaign, But only if you edit the dgen campaigns i think.
I would however love to see something like the 'distress call position' mod included in, where when the AI are under attack, they give you a grid location of there position, as otherwise its fairly pointless them saying anything, since you have no idea where the hell they are. They might as well be saying wibble wibble wibble.
