This is the technique we use. We put the class name - object name as the first part of the description. In the query panel, there is a description panel at the bottom of the screen (turned on by one of the icons at top left).
As far as populating the description field with the information, that was the original purpose I had when writing this utility … Mass update to object names / descriptions
