Group Chat Character Lorebook Triggering

I have somewhat lofty ambitions for lorebooks when I create characters. I tend to have different constant entries, such as Public, Private, Confidential, and Internal. Everyone gets to see Public, whereas Private/Confidential is inserted based on tagging and Internal is only inserted for that character.

The intent is for this to manage context shared in a group chat.

In one-on-one chats, the character naturally sees everything of its own, while the similarly constructed lorebook associated with whom I'm speaking as works as long as it's in the Chat Lore.

In group chats, each character owns there lorebooks, and while there is a setting to "join" character cards, this doesn't seem to work for lorebooks. I only see the inclusions of each character's own lorebook in their context. The goal would be to have at least the public components of each non-muted character also inserted.

Is this the wrong strategy? It is very easy to keep lorebooks portable with characters, but it would be annoying if they'd have to be manually added as Chat lore, or removed, as characters come and go. Yet it seems the *idea* of this is valid, given the option to combine character cards is present.

Seeking advice.
