First of all, I was a big fan of Panzer General and of course love this game, too

I like challenges, but I prefer realism. So even in PG I didn't like when newly bought AI units had experience. They were rookies, weren't they? And if I buy units, neither them have experience. But in PG I could set the exp for AI recruitment to 0

So is there any option to turn off the experience of enemy units bought by AI in campaigns without manipulating my prestige? (Maybe later I will play in harder difficulty, such as lower prestige etc.)
Thanks!
