Campaigns

[Outlaw Josey Wales]

Once in awhile, I pass the time playing campaigns.  I get a message about not being able to save a battle in the middle.  I end up having to replay entire turns instead of picking up where I left off.  Am I missing something?  If I am not, how much trouble would it be to implement that?  Also, I have not tried a campaign in VN, don't know if it has any, would like to see it there as well.  Also, would be cool to be able to play campaigns HTH and be able to continue campaigns even if you draw or lose.  I think I played a Civil War game that was like that.  It wasn't Tiller's.
