The only places I see the campaign starting point referenced are in the CampaignData file and the Maps_*_Map file for that particular system. In campaign 1 it's...

				Entrance 2 Obj Name                      := Terran Starbase 
Entrance 2 Offset X                      := 0 
Entrance 2 Offset Y                      := -30 
Entrance 2 Offset Z                      := 0

 ...at the beginning of Maps_Terran_Map.txt file.
And in the CampaignData file at the end of the main section it lists the starting map as 1 (the Terran system) and the entrance point as 2 (entrance 2 only appearing in the map file itself as per the snippet above).
