Cannot edit pre-existing Sims?

[SauceySims]

Hey guys. I don't know if it's possible to edit father-daughter relationships in CAS but if someone has figured out a way please let me know.
The relationship bit cheat doesn't work for me.
Let me share my story with you guys. So my sim (Kayden 1) died and I was feeling hopeless, thinking I would never resurrect him again. So I re-added him from the gallery (Kayden 2) and made a baby with Kayden's side chick. (He has two lovers) so when I successfully resurrected Kayden one, I was hoping I could edit the relationship with the baby since she does have his genetics after all. I've tried everything from A to Z including deleting Kayden 2 to leave the father slot open, but nothing works. I just want Kayden 1 to be his rightful daughter's biological father and not just her stepfather or anything like that. If anyone had an answer for me, please enlighten me. Thank you.

If she is not in his household you can't.

Otherwise use the cheat cas.fulleditmode

Make sure you use 'testingcheats on' and then 'cas.fulleditmode'.

After you enable cheats and do cas.fulleditmode you have to shift click on the sim and go to modify in cas.
