It would be great if you could tag multiple walls of the same type with one tag - i.e. you could add extra leaders to the wall tag, similar to when you add extra leaders to text. Right now, the workaround is to manually draw a detail line.
Maybe there could be a check feature, so that if you add a new leader, and the new leader is associated with a different wall type, then the tag goes blank.
The ability to have multiple leaders per wall tag would be useful in keeping floor plans from getting too cluttered.
