Can't use "sign the user up" as first step for following steps?

Hi, I remember being able to sign a user up, then create something else (like a profile or company) and link the user (as step 1) in the new thing so that they are relational, is my memory serving me wrong??

I can’t find that “use as step 1” option here for the user profile to link.
Am I missing something?
What are the workarounds?
Cheers.
