From: Texas, USA
1. Open a standard scenario in Editor
2. Go to the Main tab for that scenario.
3. First, rename the standard scenario. Then save under the new name.
4. After save, while still on the Main tab, towards the bottom on the left it says:
Lock Genaric Data...........click to Yes
5. Save again
Now, any changes you make in that same scenario to Leaders, TOE(OB), Aircraft, Ground Elements, Devices and Units are saved within that scenario. Your Generic Data for the other scenarios is not changed.
Hope this helped
