Trying to figure out the most elegant way to do this on drawing title block.  Sometimes our drawings need to have the scale of a sheet display NONE.  If I just assign a custom property to it, then it becomes "dumb" when it needs to have actual scale, the user will have to manually type scale, which can lead to errors.  Any options on the best way to implement this?  Any elegant way to have actual scale link, and be able to type in text when needed?
