Also, for some reason, the comments aren't working for me in the regular comments, so I'm forced to ask in the discussions ;-;

You start a new run. So you cant add it to existing runs.

wdym runs

its brick rigs

a new game, new start, new colony not save compatible

wish someone made a tutorial because i have literally no idea what you're talking about

A run is basically a game playthrough, and incase If you want to start a new run or a new save you can do it by, Going to the main menu of rimworld and clicking new colony.
