That's a good point, or people could "invite friends" but surely, if a party leader themselves or someone pre-existing in the group make up has indeed clear it, the button could be unclickable, to prevent the deception. Whatcha think?

On further thought, perhaps it doesn't even need an additional button, but a tweaking of a pre-existing button. For example the "Loot" selection could be adjusted for the Savage portion of party finder to lock in max number of chests.
In opposition, "Duty Completion" could be adjusted to where it's not about the chests, but essentially just the book from completing.
