Getting an overview of reinforcements

[Liebchen]

Planning for any battle rather relies on knowing what forces you have available.

So far I've mainly played the Western Front campaigns, since I'm far more knowledgeable about them.
And here reinforcements aren't that big of a deal. Unit-count is fairly low, and the map-sizes are manageable as well.

Eastern Front is considerably different. Smolensk, for example, starts with 5 (IIRC) German divisions on-map, everything else comes as reinforcements over the course of what, 3 weeks?
And while there is (obviously) the Scheduled dialog, it lists every single sub-formation individually, making it nigh impossible (or at least very tedious) to figure out when and where divisions arrive.

So is there an easier way to get a rough idea of what arrives where and when?

When I've played campaigns, I've printed out maps and drawn on them, and reviewed the reinforcement menu to hand-write a list of formations.
