Adding a level of command

[glvaca]

Hi,

I'm doing a remake of the Uranus campaign and would like to add an additional level of command. According to the manual and what I see in game in the editor, 9 levels are possible.
1. being independent units.
2. Divisional units
3. nothing
4. nothing.
5. Corps
6. & 7 & 8 & 9 higher command.

What I'd like to do is create additional Divisonal HQ's (level 3) for selected units (like German Pz Divs and Russion Tank, Mech, Cav and Riffle Corps etc...), assign level 2 units to these HQ's. And in turn assign the HQ to Corps/Armies.

Unfortunately I have not found how to create this extra level. The only way I have found is to disable the historical OOB setting but this is not ideal as it allows for unhistoristorical combinations. It also seems to break the historical reinforcement schedule.

Any pointers would be much appreciated!
Thx,
Glenn
