In gschem only a symbol is added. The database of complete = information is usefuls but I think it should be run the other way, in = gschem attributes are filled in and then a suitable entry is found in = the database and if not a new entry need to be created or more = attributes added. This method would be especially useful then ordering = information need to be changed or added.
