Add Import Sound Element Option to UI

I don't see an option to import a sound file on the interface.  Please consider adding an Import Sound file option to the bottom of the UI  under > ADD ELEMENT.  I tried dragging and dropping an .mp3 from my Mac desktop onto the stage but it didn't seem to work. The sound file just jumped back into my desktop folder and no icon appeared on the stage indicating if the file was imported.  Please advise how one can import an .mp3 file.  I also used the Search box in IB3 and typed "Import Sound" and no instruction on this important topic was returned.  Might want to add it as a help topic. Thanks much.
