Maximun battle size

[Delraich]

Sorry if this has come up before, but is there a way to limit the support points in a campaign?

I'm playing a long campaign with Germany (base size set to 1250), and after 2 decisive victories on Poland, I get 1000+ repair points and 4000 support points (current force value 2500 or so), for assault mission though. I find this slightly too much, thus my question.

Thanks.
