7. Each of the "flagx" entries must be changed. Flags 0-4 become Flags 5-9 in the new section.
8. The 'top:160px' entry becomes 'top:195px' in the new section to start the 2nd row of nation boxes.
9. The 'top:205px' entry (in the purple box below the pasted section) becomes 'top:230px' to allow room the 2nd row of nation boxes. This moves all the purchase classes down a bit. I don't think I missed any steps. Just save and exit.
It's possible you might have to save to desktop and then drag it back into the UI folder. Sometimes you're not allowed to save in the game folders.
One strange thing I've found is that sometimes the unit purchased is auxiliary, not core. It seems to be specific to the nation selected and is probably determined by the allies defined in the campaign file.
For example:
In McGuba's Poland scenario, I turned on about 10 countries for the Axis side (in the editor).
In game, I was able to purchase units from all those nations. Units from Italy, Hungary, Romania & Finland were all core. Units from USSR, Bulgaria, Blue Team & Bulgaria were auxiliary. I'm not real familiar with how the campaign file works, so I'll need to do some more testing.
If anyone has questions or my directions were not clear, please ask for clarification. Thanks for letting me ramble.
