You can tag multiple elements with the same tag. Use the Add/ Remove Host option during tag placement or for adding additional hosts (leaders) to existing tags.
You can also customize the appearance of tag leaders, adjust them together, or change the visibility of individual tag leaders. When editing labels in the tag family, use the Category Parameter filter to easily find the "Host Count" label. When a tag with multi-leaders is used, the "Host Count" label will report the number of elements tagged.
This new behavior works for Tag by Category, Multi-Category, Material Tag, Keynote Tag, and Material Keynote Tag.
