Alright, so.. What I'm looking for is basically a mod that unlocks all family friends when inviting guests to a party, but the issue is that I'm unsure if this exists as I believe I've only seen mods that unlocks the ability to invite EVERYONE, which I don't want.

Example: Sim A is trying to arrange a party, but she can only invite all of the Sims she knows, whereas I'd like for her to be able to invite Sim B's friends, Sim B being in the household also. Does such a mod exist? Thank you in advance!
