How do I pick my starter Mortys?

I just finished the Campaign today, and want to start Multiplayer. I've seen multiple posts saying that I can pick 3 of my Mortys from campaign to start with...but...when I start Multiplayer it just gives me one "Regular Morty" and nothing else. Am I missing something?

You can't anymore They removed the option to bring any mortys over from campaign with the most recent update.

It's a really dumb change and a lot of people are hoping it's reverted
