Hold Shift while clicking "Merge Identical" to merge objects based on their name/identification
You can now merge objects in two ways: a normal click merges only perfectly identical objects, while Shift+click merges any objects that share the same name or identification, even if their other properties differ. This provides more flexibility when cleaning up IFC files with duplicate named entries.
