I thought you were trying to do 2.
I don't know if there is a way to do this via WorldBuilder, but you can open the CivBeyondSwordWBSave file using a text editor (like
Notepad++) and add projects to teams there.
For example, to add The Internet you need to add the line
Code:
ProjectType=PROJECT_THE_INTERNET
somewhere in-between BeginTeam and EndTeam tags of the relevant team. Then that part of the file will look something like this:
TeamID=0 means that this is the first team usually corresponding to the first player. (This is also defined somewhere in that CivBeyondSwordWBSave file.)
You can find correct ProjectType strings in the ...\Mods\Rise of Mankind - A New Dawn\Assets\XML\GameInfo\CIV4ProjectInfo.xml file under the tag Type.
