[Dr. P.R. Park III]

I have recently created a *** and CPBL roster set, and exported them at .txt files. In the export, the game lists their "Team ID." My question is: how do I create a new game, create a league in the same exact structure so I can do an import, and then alter the new games Team ID's so that everything matches? Up to this point, I cannot figure out how to change the Team ID, only the Historical Team ID. Can anyone help?
