Hope this is the right place for this question.
I have a household I created a few days ago (I am totally new to The Sims 4 all this, though I have owned the game for a few years), and would like to create a elder and add to that household.
I have searched online, found topics about splitting and merging households, but they all see to talk about the households that are already in game, like the Landgraabs or the Pancakes.
A couple of search results said to open my gallery and select the household from there, but all that is in my gallery, that I created, are 2 earlier households I am not using.
Can I do what I have asked, or is it not possible. Thank you.
