I think that you can already do that, without a deploy editor, except for the reinforcements, which will (soon
) be possible :
- You create the map of Wagram.
- You create the OOB of Wagram for the morning (with the reinforcement 4 hours after).
- You create a second OOB of Wagram for 13.00 (which takes into account losses, and the reinforcement already there).
It is possible to save two different deployments on the same map, so you can create two scenari and save, for each one, the deployment of units of each OOB.
