Capturing foreigners

if I capture a pandoran I have to take him to a base where I have a container built or do not have to deal with it and I can take him to any base?

@Pantolomin talks you through it in this thread, where I had a similar problem: OK, how do you capture Nasties?

You don’t have to take him to any base it just automatically puts them in containment just like any other loot.
