You can add them as necessary. Click on Scenario Database under G-4|Supply.
From there click on "add scenario info" to database" on the right side menu.
From there follow the drop down and fill in the blank formats. Everything you need to enter should be with the scenario info, so it's easiest to have the scenario open as you do this. The only thing that isn't provided with the game info is the scenario size modifier, which for ACW games can be determined here:

The only thing to be wary of is to make sure you click "add new scenario" when you're done. If you click modify old scenario you'll over write and existing one. If you do that just let us know, it's not irreversible, but we appreciate not having to fix it ;)
If you have any questions or concerns feel free to contact Thunder or myself for help, here or privately.
