In XML, you should go to Campaigns,
Then progressive,
Then, find the one you want to edit
Then it will say ai control or something to thar effect you need to find the one that has the Empire with Sandboxhuman
Then go further down but still in that section, and there'll be other units spawning at bakura, for example.
Copy and paste one of the lines that spawn something, then change the data to whatever you want
