Ability to suggest a theme for engravings? I would love to have a "Hall of History" with an entire hallway engraved along the walls with historical events. When I tried this, however, I got random stupid engravings of cats and mushrooms and cheese with only 2 historical events, neither about my fortress.
Cannot be done through modding.
You COULD, however, try leveling up your engravers.
An engraver with any amount of skill (and an actual event to engrave) will make hundreds upon hundreds of historical engravings.
