I could see an advantage to this for typical details, or details that can be modified for the current projects. Engineers that I work with seem to have a numbering system, almost every detail in the drawing has a number below the title.
I think it would be useful if the number included the year it was created or modified, or an abbreviation for the job it was used in, for custom designs.
I don't consider it useful in my work, the way that details and drawings are usually one-off. I can find work by saving in the computer under the project name.
