Does anyone have the answer to the edit family relationship situation thats been going on?

I've been searching the web for an answer to this problem. It seems quite a lot of people are not being able to edit in CAS husband and wife, or sometimes any family member's role/position. It's greyed out and it just says Houshold member, and you can't adjust it. I'm trying to download sims from the gallery put them together in a house and make them husband and wife etc. But I've only been able to do this like one time and I don't know w how I done it. Some people say use the cheat Cas.fulledit mode but that doesn't work anymore I tried it. I'm on Xbox one, but I thought maybe some PC people would still have some info about this problem. I read something like download your sims but don't have them in the playable state yet, and on the manage world screen click on the lower right corner that says replace the household with the one you uploaded. then you will be able to adjust family relationships and such. I may not have fully explained it. But I'm not sure how to do what they're saying. It t seems that when you first bring a sim off the gallery and first go to cas, you can edit their relationships. But if say you have over the past week downloaded 6 sims and now you want to combine them into one big home, it will not let you edit their relationships any longer, it just says household member, and if you use the full edit cheat you can only put it on father, brother or sister. This is an issue that's been going on since idk maybe 2015 and today I still cannot find a clear answer to the problem. ((UPDATE)): I recently found out how to edit the husband wife thing. If I remember correctly, you put together a family household from gallery then get ready to put the household onto a spot, but instead go to save household to gallery, then go to the newly saved household in your gallery and add them to the household, you will have copies of them, but you should be able to change the ones just added to wife and fiancé. do that then delete the two copies that can't be changed. Now they are married, and you can place them on or in a lot. I just made this post because I was having trouble making sims husband and wife, the option was not available anymore....and I searched on the web and saw all kinds of different methods and cheats to try and do this, complicated stuff for real. most of it was on PC...And I searched for new videos for 2022 and nothing. Well just the same old complicated cheats...Well my way is easier and just thought I would share this info incase it is a concern for anybody else.
