Adding music and sound effects

I’ve been using with Final Cut Pro for a few years and I would like to make a suggestion.

When having to include effects or music in the timeline, it would be great to have a marker appear next to the music title or effects name when that track is used in the timeline of the project as shown in the attached image. For projects having many added tracks, these markers would indicate which ones are used for that particular project and would not, of course, interfere with the timeline of another project.
