Hi ,
Looking for option in AutoCAD Electrical to have parent child description auto update. 
Example: If I update the parent block description, Expecting to update automatically in child block as well.

They SHOULD update automatically, IF they have the same values initially.

If they are different, it will not update automatically. This is as designed.
